Hi Everyone! Glad to have you on board. Thank you for clicking this read. In this post today, I’ll cover Real Life Examples of Workflow Automation.
Workflow automation is a talk of mainstream conversation. Many employees use this process in their organizations but they are not aware of this term. Workflow automation is a process used to automate manual and repetitive time-consuming tasks. It requires a series of tasks that need to be completed in a sequential manner where the process goes from start to finish with a definite goal in mind. For instance, onboarding new clients and approving leave requests are susceptible to errors when done manually. However, with workflow automation software, these tasks are done automatically without human intervention, leaving no room for mistakes or failure.
In this digital transformation stage, it is almost impossible to handle the influx of data manually. This is where digital technology comes to rescue you. With workflow automation, you can streamline business processes in a way that requires less time and hard work and guarantee optimal results.
We’ve compiled 7 real-life examples that use workflow automation to bring value to your business where you can automate routine tasks, allowing you to pay careful attention to the business objectives that matter.
Expense reports are a hassle. You require these reports to reimburse the money employees pay out of their pocket. Companies need to ensure their finances and expenditures are in check to make sure they don’t go out of budget anytime soon.
When employees spend money on travel or any business purpose outside the company premises, they feel uncomfortable finding all those receipts to submit as proof of purchase. And for the finance department, this process is painful since they need to do a lot of physical paperwork and fill spreadsheets to reimburse money to the employee.
Solution? Workflow automation.
With workflow automation tool, creating expense reports are like a walk in the park. Employees can use this tool on their smartphones. All they need to do is click the image of the receipt and upload it in the app, and send it to the manager for approval. The manager can check the details at a glance and can immediately approve it and send it to the finance department for reimbursement.
The first impression is the last impression. So make it count. If new hires experience a positive onboarding process, they are more likely to stick with the company.
Manual filling of personal information and compliance documents is prone to mistakes that will leave a negative first impression on the new hires. This situation can be avoided with workflow automation.
Incorporating workflow automation software in hiring new candidates will make the process smooth and accurate, putting both executives and new team members on the same page. This way the manager you will work under can overview your background at a glance and assign tasks to as best of your capabilities.
No matter the organization, assigning new tasks to the individuals takes time and requires deliberate effort. It is very challenging to manually keep the record of tasks assigned to each individual. This is where workflow automation comes in handy.
For instance, Flokzu is a workflow process management software that you can use to visually create the outline of each task to be completed. Moreover, it comes with a reporting system that lets you know about the pending task when it is completed and automatically assigns the new task to the relevant team member.
Traditional handling of leave requests is outdated. You can’t consistently keep in check whether the company is working with a full labor force. If handled manually, you always need to enter the time when an employee is away, which is a painful and tedious job. Workflow automation makes this process effortless.
Once the manager approves your leave request, the workflow automation software will automatically monitor the time when the employee is away and make it sync with the payroll. So, the time-off duration will automatically be deducted from your paycheck at the end of the month. This way manager can keep the record of employees working in the company at the same time and those away, making sure the required number of employees are present in the organization.
Data procurement is a fundamental component of your business growth. It helps you make an educated decision around the calculated data to handle business operations efficiently. With the deep insights into the raw materials entering the manufacturing department, you can find areas of improvement immediately.
When handled manually, data procurement can lead to data loss, more time spent and reduced productivity from the labor workforce. However, automated systems, on the other hand, help you monitor data on a single screen and allow the manager to efficiently revisit the strategic decisions and improvise on them for better results.
Impeccable customer support is the prime pillar of any agency. You want to turn customers into recurring customers, which is only possible when their queries are handled and requests are answered immediately. The main purpose of any customer support is to bridge the communication gap between customers and the agency so they keep coming back for what you have to offer.
And with workflow automation, you can bridge this gap and delight the customers with consistent and reliable processes from ticket creation to ticket closure. When you submit the ticket, your request is transferred to the relevant department which might involve getting back and forth between departments until you get the email when the issue is resolved. Some companies use online chatbots where the queries of customers are handled immediately without any delay. Know that when repetitive and mundane activities are automated, team members can pay attention to value-added endeavors.
Invoice generation is necessary to balance the books of any organization. According to reports, one accountant can process 5 invoices per hour manually and charge $19.24/hour. In conclusion, one invoice costs $4 to manually process it.
With workflow automation software this cost can be significantly reduced. You can, for instance, subscribe to invoice generation software QuickBooks ($12.50/month) and can generate scores of invoices at a low cost.
If you integrate a payment platform like PayPal with an invoice generation tool like QuickBooks; whenever you buy anything, the system will cut money from the former and an automatic electronic invoice will be generated in the latter.
Workflow automation is an effective way to manage complex business tasks. But while this process is in practice, it doesn’t mean you have to adapt it anyway. What’s working for other companies might not work for you. For instance, tasks that are not repetitive and time-consuming, you might prefer doing them manually since it may require more time and budget to put them on an automated system. Similarly, the tasks like system failure or hacking, when this occurs you instantly need human involvement. Make sure you do your due diligence before incorporating workflow automation into your business, so you can reap more benefits than your competitors.

In this article, we will discuss the introduction to organic chemistry in which we will study organic compounds, classification of organic compounds, types of formulas, use, significances, general and covalent bond characteristics of organic compounds, and homologous series and his characteristics. 9 out of 10 takes the organic chemistry too tough but I explained it easily and simply to you. This article is for beginners and clears many topics.
“The chemistry of compounds obtained from living things.”
Swedish Chemist Jacob Berzelius put forward this theory in the 19th century.
“ Organic compounds could not be synthesized in the laboratory due to the influence of a mysterious force called vital force, which occurs only in living things.”
The branch of chemistry in which we study hydrocarbons and their derivatives is known as organic chemistry.
Organic compounds belong to hydrocarbons and their derivatives which are covalently bonded to carbon.
There are so many examples of organic compounds
Organic compounds had six types of formulae;
The formula In which the exact no of atoms is mentioned in one molecule of the organic compound is called the molecular formula.
Examples
The molecular formula of methane CH4.
The formula of organic compounds shows the actual arrangement of different atoms of various elements present in a molecule.
Example
The structural formula of propane is
Iso_ propane
The formula in which groups of atoms are linked with each carbon atom in a branched-chain or straight chain.
Example
The condensed formula of propane
Iso_propane. n_propane
The formula in which sharing of electrons in a dot and cross-form between the various atoms in one molecule is indicated is called electronic or Dot and Cross formula.
Example
In which whole, no ratio of different atoms in a compound gives the empirical formula of organic compounds
Example
The essential form of structure of an organic compound makes a series of atoms that are bonded together in the form of a chain, branched, or rings called the skeleton formula.
Example
skeleton formula of propane is
Depending upon their carbon atoms, organic compounds are divided into two categories.
Acyclic compounds form a long chain of carbon atoms without joining the end of the cross-format with each other. They may form straight or branched chain compounds
A straight-chain is formed by the linking of carbon atoms with another carbon atom or any other atoms through single, double, or triple bonds.
Example
propane
Branched-chain compounds
Open chain compounds i.e. aliphatic compounds in which a branch along with a straight chain is formed.
Closed chain or cyclic compounds
The carbon atoms of closed chain compounds are not free from their ends and it contains one or more close chains. These are divided into two groups
These compounds are made up of rings of carbon atoms. These are further divided into two groups.
Aromatic compounds consist of benzene rings at least one in their molecule. Six carbon atoms with three double bonds make a benzene ring, these compounds are also called benzenoid compounds. They have aroma or smell so they are also called aromatic compounds.
Example
These are called none_ benzenoid compounds because the benzene ring is not present in these compounds.
Example
Those cyclic compounds that consist of one or more atoms other than that of carbon atoms in their rings are known as heterocyclic compounds.
Example
The classification of known compounds is as follows
so the organic compounds are open or closed chains. Open chains are further divided into alkane, alkene, and alkynes. Closed chains may be homocyclic or heterocyclic. Homocyclics are alicyclic or aromatics.
From plants and animals, organic compounds are naturally prepared.
Protein and fats are the two major groups of organic compounds that are synthesized by animals.
Plants could be prepared
From dead plants through a biochemical process, we obtain
By the destructive distillation of coal and petroleum, we obtain thousands of organic compounds.
A blackish, complex mixture of organic compounds of carbon, hydrogen, and oxygen is called Coal
In the absence of air, strong heating of coal is called Destructive distillation.
Except for carbon, coal contains different elements like hydrogen, oxygen, sulfur, and nitrogen.
So huge number of organic compounds are formed due to the destructive distillation of coal with few inorganic compounds.
When coal is passed through the destructive distillation process. A solid residue left behind and lost all of its volatile elements is called coke.
The techniques, in which different ranges of temperature are used to separate the mixtures of the coal in terms of temperatures. we get different products at different ranges of temperature.
The below chart shows the uses and types of coal
A Greenish black or dark brownish colored viscous liquid is called petroleum.
It is a complex mixture of salt, water, and Earth particles mixed with a mixture of serve solid, liquid, or gaseous hydrocarbons.
The main source of organic compounds is petroleum and it is separated through fractional distillation. Different organic compounds consist of each fraction of petroleum that is not a single compound.
Natural gas consists of serial gases like 85% of methane, nitrogen gas, carbon dioxide, propane, butane, and ethane.
Macromolecules are formed by living plants
Two centuries ago, due to the vital force theory, we considered that organic compounds are prepared only from animals and plants and could not be synthesized in the laboratory.
A large amount of the organic compounds, almost more than ten million are synthesized in a laboratory.
Urea opens the way for chemists to prepare organic compounds in the laboratory and it is synthesized by inorganic salts.
Example
The fermentation of barley and molasses produced alcohols.
Synthetic rubber has much more qualities than natural rubber-like
Different fibers are made in laboratory-like
Natural fibers have better properties than synthetic fibers like
All proteins, sweeteners, vitamins, drugs, and medicines are being prepared in laboratories.
There is no doubt that more than ten million compounds are made in the laboratory but thousands of organic compounds are naturally synthesized by plants and animals.
We use different organic stuff daily such as milk, eggs, vegetables meat, etc. contain protein, vitamins, fats carbohydrates, etc.
Natural fibers and synthetic fibers, all are organic compounds used in cloth making that we use daily for wearing bedsheets, etc.
A variety of organic compounds are used in raw materials such as
cellulose naturally occurring organic compound in wood that is used for making furniture and housing.
Coal, petroleum, and natural gas are all organic compounds called gospel fuel that is used for domestic purposes and automobiles.
antibiotics (kill or inhabitants of microorganisms that cause infectious diseases) are life-saving medicines.
The general characteristics of Organic Compounds include:
A covalent bond is a chemical bond that influences the sharing of electrons pairs between atoms in a switch resulting in a balance of impressive and despicable forces between the atoms. The presence of a covalent bond renders specific elements to the organic compounds. These include:
A major characteristic of Members of Homologous Series
A Homologous Series is a community of organic chemical compounds, usually summarized in the order of increasing size, that have an identical structure (and hence, also similar properties) and whose structures vary only by the number of CH2– CH2 units in the fundamental carbon chain.
They maintain the following general characteristics:
So this is all for our today's article. I have tried my best to explain all the important topics covered in the heading " Introduction to Organic Chemistry". So if you want more tough articles in simple ways then give me good feedback. It will help me for better work. Thanks
Hi Friends! Hope you’re well today. I welcome you on board. In this post, I’ll walk you through How Workflow Automation Can Benefit Small Businesses?
Reduce the possibility of human error, save time and improve efficiency – The main goal of workflow automation. If your employees spend a lot of time on mundane and repetitive tasks, it’s a high time to invest in workflow automation. Especially if your business is small and you are in the early stages to leave a footprint in the competitive market. You can’t afford to hire scores of employees to do predictable tasks that you can automate with workflow automation. For instance, follow-up emails and sales calls, finance approval and invoice generation, and onboarding new employees, you can automate these tasks without having to worry about hiring someone to handle them manually.
Curious to know how workflow automation can benefit small businesses?
Keep reading.
Before we proceed further, we’ll cover what workflow automation is?
Workflow automation is the process to automate manual repetitive tasks to improve efficiency and reduce human error. When you apply technology to business operations, you can effortlessly translate the manual handling of processes into automation. This way employees can spend more time on value-added tasks that require a human touch and brainstorming.
What’s more, with workflow automation you can monitor employees’ performance and can immediately apply tweaks to revisit your strategic decisions. Plus, you don’t need a technical IT team to streamline processes, improve reporting and integrate two or more apps. Apps like Zapier do it for you. It involves creating Zaps that is creating links between business tools. For instance, it can integrate a website, CRM software, and messaging app to improve productivity and bridge the communication gap between customers and the agency.
The following are the core benefits of incorporating automation into your business.
Chasing down people across departments is so frustrating, especially when you don’t know the current status of the file. With workflow automation, you can monitor the workflows online and get an instant alert to set priorities. This improves the productivity of the employees, allowing them to be better prepared for the pending tasks.
Employees are the backbone of any industry. But you need to keep your budget in check while getting employees on board. You can significantly reduce the cost of labor workload if you automate some of your business processes. For instance, freeing employees from doing predictable and mundane tasks will help you invest in the things that involve human input.
When employees are free from manual tasks such as data entry, form filling, and invoice generation, they will find more time for brainstorming and get creative on the tasks that require innovation and emotion. The potential to apply intelligence, sensitivity, and expertise on the product level allows companies to deeply connect with the customers and deal with their questions and queries with deliberate intention.
When the pandemic hit, the demand for remote work increased more than ever before. Not everyone can manage to do an in-house job in a time of crisis. Companies that know how to manage the workforce remotely can effectively capitalize on the given resources. With workflow automation, you can seamlessly connect employees from different parts of the world. For instance, Google Drive, and DropBox allow the companies to share files across departments, and tools like Loom allow them to have full visibility of the teams.
What tasks do we need to automate? The answer is simple: Tasks that are repetitive and require approvals and smooth communication. Following are the five tasks that you can automate in your business.
At times employees have to spend money on the best of money for business purposes. Companies can’t instantly pay those employees who pay out of their pocket. And when they apply for reimbursements, they come across a hassle process especially when reimbursements are handled manually.
To effectively handle such scenarios, automation is the solution. Incorporating workflow automation prevents employees to chase hectic approvals and make regular visits to the finance office. Automation makes this process straightforward. Employees simply upload the receipts on the software which instantly gets connected with the manager for approval. Once the manager grants approval, receipts move to the finance department and they release the money spent by the employees.
First impression is the last impression especially when it comes to onboarding new hires. The seamless onboarding process tells a lot about employees if they are going to stick with the company for a longer time.
Tasks like updating new hires, documents approval, and follow-ups can be automated before candidates even join the company. Plus, you can effortlessly communicate and assign them the tasks so they are better prepared when they embrace the new role. Automation removes the tedious paperwork and mundane approvals, allowing both employer and employees to come on the same page without the need to back and forth face to face interaction.
Every organization deals with the influx of leave requests regularly. If organizations still use traditional ways to approve requests, they might already know it’s a tedious process. At times manager feels difficulty in managing the required number of employees in the company. One employee might want the same day off already applied by another employee. If handled manually, it is very challenging to keep the record of employees with days off or those who want particular time away from the company.
Workflow automation removes this uncertainty and makes sure the company doesn’t go understaffed. Automation software tracks and keeps the record of the time of those away and the manager can instantly approve the leave requests by scanning everything on the single screen. Software is stuffed with an online form to let employees know which days are available or unavailable that automatically limits two employees requesting the same days off.
No matter the type and size of your business, data procurement is a critical part of every business. It is a process that consists of a series of functions required to obtain goods and services from the vendor and keep a record of how these services and goods are used to achieve business goals. The effective use of the procumbent function directly influences the cost-saving objectives of the agency. Yes, by analyzing the data you can revisit decisions if you need to change vendors and suppliers. Data procurement goes beyond the purchase of goods and services. For instance, it also includes a better understanding of the performance of all business units, supplier performance, risk and compliance management, and contract utilization.
Manual processing of data procurement often leads to compromised risks like operational risks, delivery risks, and potential frauds. Moreover, inaccuracy and inefficiency are other issues that result from the manual handling of data. However, with automation procurement software these issues can be avoided. Automating vendor management and purchase orders guarantee enhanced compliance and greater productivity.
Invoice generation is an integral part of any business. Effective invoice generation builds trust and allows clients to stay in touch with your business and keep coming back for what you have to offer. If you create invoices manually, you might need to generate an invoice every time to request payment from the client. However, with workflow automation this process becomes transparent, preventing you from entering information every single time to request the next payment. A smart automation solution comes with automation of data entry, matching prices, transferring digital payments, managing purchase orders, and more. Generating digital invoices is crucial for businesses to keep up with the modern trends and compete with rival brands.
When you start a small business, you need employees to keep it up and running.
However, it’s probable in the early stage of your business you’re tight on budget.
To combat this, a smart automation solution is key.
No advanced automation solutions are required. Some vendors offer low-cost solutions that perfectly fit your budget.
From vacation requests and invoice generation to data procurement and onboarding new hires, you can automate workflows for your business growth.
Know that not every business task requires automation, since some mission-critical tasks like system failure and hacking demand instant human involvement to run a business without delays.
That’s all for today. Hope you’ve enjoyed reading this article. If you have any questions, you can ask me in the section below. You are most welcome to share your experience of incorporating workflow automation into your business. Thank you for reading the article.
Hello readers, I hope you all are doing great. In our previous tutorials on raspberry pi Pico, we discussed the basic features, architecture, download and installation of development environments for raspberry Pi Pico programming. In this tutorial, we will learn how to access and control Raspberry Pi Pico and its GPIO pins to implement LED blinking using MicroPython.
Raspberry Pi development boards are quite popular and frequently used among students and hobbyists. But the drawback of Raspberry Pi is their cost i.e., around $35-$45. So when cost of the development board is of prime importance the users prefer to use ESP8266, ESP32, Arduino, PIC etc. over Raspberry Pi. To overcome this drawback, Raspberry Pi foundations designed a new board i.e., Raspberry Pi Pico which is a cost effective solution for costlier Raspberry Pi boards.
Raspberry Pi Pico is a cost-effective development platform designed by Raspberry Pi which has enough processing power to handle complex task. It is a low cost and yet powerful microcontroller board with RP2040 silicon chip.
We have already published tutorials on how to download and install the above mentioned software components.
Follow the given link for detailed study of Raspberry Pi Pico: https://www.theengineeringprojects.com/2022/04/getting-started-with-raspberry-pi-pico.html
We have already published a tutorial on installing Thonny IDE for Raspberry Pi Pico Programming. Follow the given link to install the IDE: https://www.theengineeringprojects.com/2022/04/installing-thonny-ide-for-raspberry-pi-pico-programming.html
The Raspberry Pi Pico board comes with an onboard LED which is internally connected with GPIO 25. So first we will discuss how to access the on board LED and then will interface an external one.

The evolving generation of wireless technology has made human life a lot easier. Where everything is online and automatic we can easily monitor multiple things virtually from anywhere in the world. The WSN (wireless sensor networks) and Internet of things or IoT play an important role in implementing and accessing these wireless technologies. Smart homes, smart cities and smart weather monitoring systems are examples of such technologies where things are quite simpler or easier.
In this web-server based weather monitoring system, the weather data (from the surrounding environment or of a particular location) like temperature, humidity, pressure etc. is measured with the help of some sensors and then the collected data will be stored on a server after being processed by a microcontroller. Our daily activities are inseparable from weather conditions and various environmental factors. The real-time data collected can be used in research and analysis and the results can be helpful in human life and for improving environmental conditions as well.
The Internet of Things is a system made up of multiple inter-related computing devices. The main factor ‘things’ in IoT is designated to a component that is capable of communicating data over a network (IoT), the thing could be animals, a digital machine, a sensor, a human being etc. Each component of the Internet of Things network is given an individual or a distinct identity and the ability to communicate data or information over a wireless network that is too without the intervention of a human or a computer [8].
An interface medium capable of collecting, controlling, and communicating data among transmitter and recipient electronic equipment or servers is required to build the IoT network[9].
The ESP32 microcontroller series was developed by Espressif Systems. This module (the ESP32) includes a 2.4GHz Wi-Fi chip, memory, a 32-bit Tensilica microcontroller, an antenna, peripheral interfacing abilities, power management modules, and more. This ESP32 module is excellent for the Internet of things because of all of its technological and infrastructural aspects [10].
DHT11 and BMP280 sensors are used to collect the data from their surrounding environment and then communicate the data to the ESP32 module over a particular protocol [11].
The application of this weather monitoring system can also play an important role in the field of agriculture[12 ] to increase productivity, research application, and reducing manpower (by reducing the need to manually monitor the field status). Sometimes in a particular agricultural zone that is hazardous for a human beings, it is quite difficult to manually (offline) monitor the environment or weather conditions. In such cases, this web server based or online weather monitoring system can be of great importance.
Fig. 1
The list and quantity of the components required to implement the web server based weather monitoring system are shown in Table1.
Table: 1
Fig. 2 DHT11 sensor
DHT11 sensor (or temperature and humidity sensor) is a sensor module used to measure humidity and temperature from its surrounding. This sensor module is responsible for monitoring the ambient temperature and humidity of a given area. An NTC (negative temperature co-efficient) temperature sensor and a resistive type humidity sensor make up the sensor. An 8-bit microcontroller is also included. The microcontroller performs ADC (analogue to digital conversion) and outputs a digital signal via the single wire protocol [13].
Some of the technical specifications of the DHT11 sensor are:
Table:2 DHT11 technical specifications
DHT11 sensors can also be used to create a wired sensor system with up to 20 meters of cable.
To measure temperature and humidity, two DHT modules (DHT11 and DHT22) are available on the market. Both modules serve the same purpose, but they have different specifications. The DHT22 sensor, for example, has a wider range of temperature and humidity sensitivity. However, DHT22 is more expensive than DHT11. As a result, you can choose to use any of the modules as per your needs.
Table.3 Interfacing DHT11 with ESP32
Another sensor we are using is the BMP280. The BMP280, also known as the barometric pressure sensor, is a temperature, pressure, and altitude sensor. This sensor's small size and low power consumption make it suitable for mobile applications, GPS modules, and battery-powered devices, among other things[15].
The Bosch BMP280 is based on Bosch's validated ‘Piezo-resistive pressure sensor technology’, which features high accuracy, long-term stability, linearity, and EMC robustness.
The barometric pressure sensor (280) is the successor to the BMP180 sensor, and it is mostly preferred in all areas where precise temperature and pressure measurements are required.
Fig.3 BMP280 Sensor
Fitness, indoor navigation, and GPS refinement are all new technologies which require relative accuracy, and the BMP280 is ideal for them. This module is preferred over the other available modules for temperature records or measurement because of its low TCO (Temperature coefficient of Offset).
The temperature measured with the BMP280 sensor is more accurate than the DHT11 sensor. BMP80 provides a 0.01°C accuracy rate.
Some technical specifications of the BMP280 sensor are:
Table:4 BMP280 Technical specifications
A web server is a place where one can store data online and can access that data at any time and from anywhere in the world [16]. A real-time data is created with the help of a web-server. There are various web services available to store real-time data for research and analysis like AWS (Amazon Web Service), Azure, Firebase etc.
We are using the ThinSpeak web service provided by MathWorks which allows us to send sensor readings/data to the cloud. The ThingSpeak is an open source data platform for the Internet of Things (IoT) applications. We can also visualize and act on or access the data (calculate the data) sent to the ThingSpeak server from ESP32. Two different types of channels are available to store data on the ThingSpeak server namely ‘Public Channel’ and ‘Private Channel’ and one can use either of the available channels to store and display data [17].
ThingSpeak is frequently used for IoT prototyping and proof-of-concept systems that require analytics[18].
We need to give instructions to our ESP32 module so that it can interface, read data from DHT11 and BMP280 sensors and then finally publish the collected data to the ThingSpeak server. Arduino IDE is an integrated development environment used to write, compile and debug the program for the ESP32 module[19].
Fig. Arduino IDE
The process flow of our weather monitoring system is shown below in Chart 1. The process starts with the initialization of ESP32 module which is acting as an interface medium between the sensor modules and the web-server. The ESP32 wi-fi module is continuously searching for the network credentials as per the instruction provided. After connecting to the internet the sensor modules will be initialized and the real-time data [22] collected from the surrounding environment will be pushed to the ThingSpeak web server[23].
Flow Chart: 1
The results observed from the implemented weather monitoring system are shown below. We observed four different environmental conditions which include temperature, humidity, pressure and altitude. The sensor data collected by ESP32 from DHT11 and BMP280 sensors is published to the ThingSpeak web server. On ThingSpeak we have created a channel that contains four fields to store four different environmental factors temperature, humidity, pressure and altitude.
Fig. Hardware
In fig. 4 we can see the ‘Field 1’ which is containing the temperature readings published or communicated from the ESP32 module and saved on the ThingSpeak server.
Similarly, fields 2, 3, and 4 are displaying the humidity, pressure and altitude respectively.
Fig. 4 Temperature (°C)
Fig. 5 Humidity
Fig. 6 Pressure (hPa)
Fig. 7 Altitude
Each factor is monitored at different intervals of time to observe the variations in various environmental factors. From table 5 we can see the various environmental factors and their values at different time intervals for the approximate duration of 24hrs.
Table 5 Variations in weather conditions
We observed the weather conditions (that includes temperature, humidity, pressure and altitude) with our “Web-server based weather monitoring system using ESP32”. The observed real time data is stored on the ThingSpeak server which can be accessed globally. The different values of each (mentioned earlier) environmental factor at different intervals in time are also observed (given in table 5) and the observed result clearly shows the changes in the weather conditions for a full day cycle. Hence, we have successfully implemented and tested the web server based weather monitoring system with ESP32 and ThingSpeak web server.
Storing and analyzing big data is essential for process audits. For example, a company’s ongoing shipping audits explained several issues, including patterns of overcharges and delayed deliveries. A customer experience audit can yield similar findings by noting bottlenecks in the customer journey. All of these processes require the input of large sets of readable data.
Businesses need a data normalization process to store and filter raw data into useful information that can inform these valuable processes.
Data normalization is an automated process that organizes information into a database or table. As a result of normalization, data is searchable and verifiable. Normalized data is also easier to scan for errors, such as missing data or redundancies.
Most data normalization tables categorize data by recognizable fields. For example, a table of customer information would most likely contain their names, contact information, and job titles. Company data may contain labels such as product SKUs or employee identification numbers.
Data normalization tables prevent a phenomenon known as inconsistent dependency. This occurs when unrelated data items are entered in the same table. Data input should be logical so that anyone searching for a piece of information knows exactly where to find it.
Many software-as-a-service platforms, such as invoicing or customer management solutions, automatically normalize data. To reduce errors in automated normalization, companies must set a standard format for inputting data. Some commonly used conventions are abbreviations for addresses and job titles, or no hyphens or spaces in telephone numbers. Once data is normalized, it is easier to carry out important data analysis processes, including cleaning and interpretation.
Normalization tables come in several normal forms, known as NFs. Each NF has its own rules for organizing and displaying data. For example, a 1NF table restricts any cell from containing more than one piece of data. Additionally, no entry can be duplicated.
For example, if a data table contains a product that comes in several sizes, each size will be listed as a separate row rather than a distinct column. In a 2NF table, the searcher can pull up a separate table to view all of the color options for a particular product.
As normal forms advance, they build off one another. A 2NF pulls data from 1NF tables, a 3NF from a 2NF table and so on. While there are many normal forms to choose from, most databases only need up to 3NF to process and store data.
Choosing the correct normal form and preparing the data can be time-consuming. As a result, more developers opt to outsource this process to automated software.
As data collection has become ubiquitous, data normalization has become indispensable. Firstly, normalization corrals data into one depository. This reduces storage space by eliminating duplicate information. Browsing through normalized data also saves time as databases contain search functions that quickly identify the needed information.
Normalized data also lends itself well to segmentation. During segmentation, the analyst will filter the data through parameters, such as location, gender, or average purchase value.
Segmentation allows marketers to target specific demographics with tailored messaging. This process can also benefit internal business processes. For example, human resource departments may search for employees demonstrating signs of burnout, such as higher than normal call-outs, and connect them to resources.
Data normalization is also essential for monitoring metrics and performance. Normalization makes it possible to create visual dashboards to measure common indicators such as sales targets, vendor costs, and revenue.
Data normalization is an essential step in any business’s data strategy. As a developer, you can make you and your client’s jobs much easier by considering normalization as you create your projects and database structures.
Most developers follow the decades old principles created by relational database pioneer Edgar Codd. Codd’s 12 rules, since expanded to more than 300, outline the existential criteria for relational database management systems. While no system follows every rule, they are a foundational step for approaching normalization projects.
Hi Guys! Hope you’re well today. I welcome you on board. In this post, I’ll walk you through Introduction to Workflow Automation.
Workflow automation is a critical part to run a successful business. It is used to improve the efficiency and productivity of the business to provide a better user experience, reduce errors and increase revenue. Workflow automation is the process of automating a set of repeatable tasks to achieve a certain goal within the software or app you use.
Confused?
Don’t be.
We’ll touch on this further in the article.
Curious to know more about workflow automation, its benefits, how to choose workflow automation software, and how it can help your business?
Keep reading.
Before we get into the nitty-gritty of workflow automation we must know what workflow is.
Every business is based on a predefined process. It’s the set of activities including manual tasks like creating reports, data transfer, collaborating within the company and more… all these tasks are performed to fulfill the business needs. Workflow guarantees all these processes are planned and executed in a sequential manner by the people or systems to achieve a certain goal.
Know that a workflow image can be a simple flowchart diagram representing a set of activities to reach the desired goal.
And automation is the process that repeats itself without human intervention. It works on WHEN and THEN rules. For instance, when the temperature falls below 30 C, then turn on the AC.
Simply put, workflow automation is automating the workflow – it involves incorporating the automated software system within the company to monitor and control business processes. The software is used to perform a repeated set of steps consecutively to do a certain task. In this process the work goes from start to finish without human involvement, eliminating the manual steps and ensuring the error-free work on time.
The workflow automation you can implement in the business processes includes sales and marketing, human resource, lead management, and more. This way businessmen can pay careful attention to the more important tasks rather than worrying about properly executing the workflow within the software.
The key benefits of workflow automation include:
Choosing the right workflow automation software is a bit tricky. It depends on the workflow processes you want to manage within a business.
There are two types of software used in workflow automation: no-code tool and low-code tool.
The no-code tool works better for the beginner with no technical expertise. Some of these tools come with a drag and drop feature, allowing you to easily customize the workflow for your business process at hand. The low-code tool, on the other hand, requires coding skills to put into practice. Low-code tool doesn’t mean you have to be a tech-geek to get a hold of it. And you don’t require any software degree either, you can learn it easily if you put a deliberate effort and attention.
Other things you must consider while choosing the right tool include:
The tool comes with easy to handle user interface UI which means you can learn it yourself, if it requires technical support at every step, you better skip it.
The tool must be economical and scalable so you can modify it as per the business processes.
The tool must be compatible with your apps. What may fit for other businesses might not work for your business. If everyone is buying it doesn’t mean you also have to buy it. Keep your business processes in mind before choosing the right tool.
Workflow automation sets you free from doing manual repetitive tasks and automates your business processes to improve efficiency and productivity.
Following are the key areas of your business you can automate with workflow automation:
Invoice generation is a crucial task to create a document to bill your clients. When done manually, mistakes are obvious. But with workflow automation, you can automate the invoice generation process to bypass the multiple manual processes. You can use workflow automation software to create the invoice to bill the client month after month for a definite amount. Plus, you can keep a record of the invoices you create for a particular client.
Onboarding new candidates is overwhelming at times. It requires a lot of brainstorming, resources, workforce, and time. However, with workflow automation, this process can be straightforward without the involvement of repeated manual processes. Workflow automation software allows the new candidates to list their information and submit it directly to the HR department. It removes the need for manual tests and check-ups to reach the hiring manager, effortlessly bridging the gap between the company and new candidates.
Quality leads form the basis of any business growth. Manual lead management requires a lot of data filtering and manual follow-ups that slow down the process of reaching potential clients.
Workflow automation allows the companies to discard the low-quality leads, and automate the process to turn the visitors into customers. Moreover, it allows the sales team to streamline the sales funnel process, stuff CRM with the required information, direct new leads to the sales manager, and effectively deliver the products to the customers.
Manual handling of staff expenses is a tedious job. But workflow automation is here to rescue you. At times you spend money on the behest of the company. If you want to have approved those expenses from the company, first you need to write the email to the manager who will approve it and then send it to the accounting department. Everything will be documented in a report before the accounts department refund the money to the employees. However, workflow automation software can simplify this and other manual processes including creating reports, managing travel tickets, approving leave and vacation requests and producing purchase orders, and more.
A workflow automation software is an important tool for your business growth.
Using this tool, redundant tasks are eliminated and repetitive and manual tasks are put on auto-pilot.
Whether or not should you pick the automated workflow software for your business is a tricky question and unfortunately, there is no simple formula to figure this out. However, the business processes that can use automation to drive value include time-bound activities, manual repetitive tasks, lead management, customer support and data entry jobs, and more.
Keep two things in mind while picking the right tool: it meets your business's core objectives and it should be economical.
That’s all about the Introduction to Workflow Automation. If you have any questions in mind, you may ask me in the comment section below. I’ll help you to resolve your query. Keep sharing your feedback and suggestions to help us improve the quality of our content. Thank you for reading this article.
Hello friends, I hope you all are having fun. Today, we are going to share the 7th tutorial of Section-III in our Raspberry Pi Programming Course. In the last tutorial, we interfaced a DHT11 sensor with Raspberry Pi 4. Today, we are going to interface another temperature sensor i.e. DS18B20 with Raspberry Pi 4.
DS18B20 is a popular temperature sensor especially in severe/critical environments i.e. chemical plants, mines, industrial sites etc. because of its 1-wire operational technique and accurate readings up to 4 decimal digits.
Today, we will interface a DS18B20 temperature sensor with Raspberry Pi 4 and will display the values on a 16x2 LCD.
Let's have a look at the components required for this project:
Here's the list of components:
A waterproof variant of this sensor is also available, which encloses the sensor within a cylindrical metal tube. The sensor depicted in the above image will be used in today's project. The sensor's specifications are shown below.
A wide variety of temperature sensors are available. The following are the two most common kinds of temperature sensors:
Contact sensor: Some thermometers use direct contact with an object, referred to as "contact type temperature sensors," to measure the degree of warmth or cold.
Non-Contact sensor: This type of thermometer does not touch the object it is measuring; instead, it measures the temperature based on the radiation emitted from that object. DS18B20 is a non-contact temperature sensor.
Here's the circuit diagram of the DS18B20 temperature sensor and a 16x2 LCD display, connected with Raspberry Pi 4:
Now, let's design this circuit on a breadboard with the help of Jumper wires. When everything is connected, my hardware will look like this.
We have designed our circuit, so it's finally time to write the Python code for DS18B20 with Raspberry Pi 4:
Before start working on our code, we need to first install the LCD Python library and enable the 1-wire protocol in RPi board.
We need to install Raspberry Pi's Adafruit LCD library to display the temperature on the LCD screen. Using Adafruit's library, we can easily operate the LCD in 4-bit mode. So, follow the below instructions to install Adafruit Python Library:
Any project on GitHub can be cloned using Git. Since the library is hosted on Github, we'll need to set up a Git before installing this library.
That's all there is; the library should now be operational. In the same way, let's install the 1-wire library for DS18B20 sensor.
If we want to connect with the DS18B20 sensor via a One-Wire approach, we must have to enable the One-Wire Protocol in Raspberry Pi first. So, follow the below instructions:
This is what you can expect to see in your terminal windows:
You can see the sensor's readings on the terminal as a result of these commands. The image below shows a red arrow pointing to the temperature. The current temperature in my home is 37 degrees Celsius.
Here's the complete Python Code to display the temperature from DS18B20 on an LCD display with Raspberry Pi 4:
So, let's understand this Pi code for LCD display and One-Wire communication. I've broken down the code into smaller, more digestible chunks below to make it easier to understand.
DS18B20 Python Code Explanation
Importing the necessary header files is always the first step in a new program. Time and the LCD header are imported here to use the LCD with Pi.
It is important to mention the Display pins linked to the Raspberry GPIO. Consult the diagram above if you're unsure of the pin numbers for specific GPIO pins. Once the pins on the PI to which the LCD is connected have been declared, use these lines of code to initialize the LCD display.
Once the LCD has been initialized, we show a sample text message. To indicate a new line, the character 'n' is used. There is a delay of two seconds before users can begin reading the intro message.
Make sure you remember what you did in step 4 in order to enable the one-wire interface on your Pi. For this reason, we are using the os.system function to repeat the code. Afterwards, a file path is supplied where the temperature value will be read from. We can't open the folder since we don't know its exact name. The device folder variable connects to the '28-' folder using the * symbol. The temperature value is stored in a file with the name device file, which is also in that folder.
Then we create a get temp method, which specifies how to read the temperature from the file we previously linked. There will be a file containing the temperature data; however, the format will be as follows:
We only need the temperature value, which is 37000, from this. A reading of 37.00°C can be seen in this instance. After trimming all the unnecessary information from this type of text, we must next divide 37000 by 1000.
Using the lines variable, the file's lines can be parsed. A search for "t=" is done in these lines, and in the variable temp string, the value that comes after that letter is recorded. Finally, we perform division on the string value with 1000 in the variable temp c to obtain the temperature value. Finally, the code should output the temp c variable.
To display the current temperature on the LCD panel, we merely need to invoke the previously described function inside the infinite while loop. Every second, we refresh the LCD display to show the current value.
Use the code provided at the end of this page to compile it on your Raspberry Pi and see what happens. Before running the application, Install the display libraries and enable a one-wire connection on the Pi. You can now run the application and see if everything went well; if so, the intro text should be visible. Adjust the contrast potentiometer, if necessary. What you'll see when it's all done is shown in the below images:
Temperature sensors can be used in a variety of ways, so here are some examples.
In this lesson, we have studied how to use Raspberry Pi's GPIO pins to connect DS18B20. In addition, we looked into the sensor's fundamental principles and current-day usefulness. We also designed a circuit that we later programmed to collect temperature readings using the temperature sensor and perform a little calculation and display it on the LCD screen in degrees Celsius. In the next tutorial, we will interface the BMP180 Air Pressure sensor with Raspberry Pi 4. So, stay tuned. Have a blessed day.
Hello friends, I hope you all are doing great. Today, I am going to share the 6th tutorial of Section-III in the Raspberry Pi Programming Course. In our previous tutorial, we have seen how to interface an Ultrasonic Sensor with Raspberry Pi 4 and used Python to perform its calculations. In today's tutorial, we'll discuss how to interface a DHT11 temperature and humidity sensor to a Raspberry Pi.
So, let's get started:
Here's the list of components, we are going to use in today's circuit:
DHT11 is a low-cost digital sensor, used to measure temperature and humidity in the surroundings. DHT sensor has three main components i.e.
Now, let's have a look at the Pinout of DHT11 sensor:
DHT11 has 4 pins in total, which are:
The DHT11 timing diagram is shown in the below figure:
This device uses a thermistor to monitor temperature and a capacitive humidity sensor to measure relative humidity. A humidity-detecting capacitor's electrodes are separated by a dielectric substrate that retains moisture. When the humidity level fluctuates, the capacitance value changes as well. Analog resistance values are measured, processed, and stored by the IC, which then translates them into digital values.
The resistance value of this sensor is monitored, as it warms up using a negative temperature coefficient thermometer(NTC). This sensor is commonly made of semiconductor ceramics in order to achieve a higher resistance value even at the smallest temperature change.
With a 2°C precision, the DHT11's temperature range is 0 to 50 degrees Fahrenheit. This sensor can accurately monitor humidity levels from 20% to 80% with a 5% degree of precision. One reading per second, or 1Hz, is the sampling rate of this sensor. The microcontroller DHT11 has a power consumption of 3 to 5 volts. The maximum amount of current that can be drawn during a measurement is 2.5 mA.
The sensor and the microcontroller are connected via a 5K to 10K ohm pull-up resistor.
There are many types of temperature sensors available. Factors involved in selecting a correct sensor are: what we're measuring, how precise we need it to be, and where we're taking the readings. The Negative Temperature Coefficient (NTC) thermistor, thermocouple, semiconductor sensors, and Resistance Temperature Detector(RTD) are the most commonly used temperature sensors.
With its dual-row flat, no-lead SMD design, Grove's new AHT20 temperature and humidity sensor is ideal for use in reflow soldering applications. In addition to the standard temperature sensor, the AHT20 has a capacitive humidity sensor made by MEMS semiconductors that is more accurate than the standard sensors.
Digital sensors can monitor temperature as well as relative humidity. Two measurements are converted into a digital signal via an analog-to-digital converter chip. Temperature sensors with long-term stability and great performance are among the most popular.
Both temperature and humidity are monitored by the DHT22, quite similar to DHT11. The DHT22 costs a little more because it has a wider temperature and humidity range than DHT11, making it more precise. In terms of how it's handled and coded, the DHT22 is identical to DHT11. A temperature sensor that performs better and is more accurate should definitely be considered.
When compared to the DHT series, the BMP280 has the capability to measure both temperature and barometric pressure. You can use this in both SPI and I2C modes, making it an upgrade from the BMP180. Because the air pressure changes with elevation, it can estimate a location's altitude as well.
While the BMP280 only monitors temperature and air pressure, the BME280 has a humidity measurement in addition.
DS18B20 is a one-wire temperature sensor and gives accurate values up to 4 decimal digits.
AF5485 is a small and light-weight sensor but it has an impressively complex internal system that allows it to provide the best accuracy. Building automation, weather stations, and temperature monitoring are just a few possible applications.
Compact and lightweight, the AM2311A is an auto-calibration module that consumes minimal power. Furthermore, it is capable of transmitting data at distances greater than 20 meters. It goes without saying that this sensor is extremely dependable and stable over the long run. As a result, it can be employed in a variety of settings.
As you can see in the above figure, the circuit diagram is quite straightforward. To avoid noise in the DHT11 output, a 5K pull-up resistor is connected to the Data Pin. The temperature and humidity readings are transmitted as serial data through this pin.
We have also placed an LCD 16x2 to display the values. We have already discussed LCD Interfacing with RPi4, but in that tutorial, we used data pins to write on the LCD, but today, we will use an I2C LCD and send the data via I2C pins.
To connect the DHT11 sensor to the Raspberry Pi, the following steps must be followed.
Now, Raspberry Pi 4 has to be connected to the 16x2 LCD screen:
All our modules are powered up, so everything's correct. Now it's time to write the Python Code for getting DHT11 values and displaying them on the LCD screen:
We need to install the DHT11 Adafruit library to read the sensor values from Raspberry Pi 4.
Now let's design our Python code:
Here's the complete Python Code to read the data from the DHT11 sensor using Raspberry Pi 4:
Let's understand the code line by line:
Monitoring or controlling environmental quality is the main goal of environmental monitoring. The DHT11 humidity and temperature sensors are widely used in such systems.
Since this temperature sensor is inexpensive, it can be used in low-cost but effective weather stations that show the temperature and humidity of the surrounding environment.
Climate control is a method of managing the temperature. So, the DHT11 temperature and humidity sensors may be useful in ensuring that the environmental readings are accurate. Temperature and humidity sensors are sent to the microcontroller, and the system will respond if the temperature exceeds a predetermined upper or lower limit.
In this tutorial, we have studied how to connect a DHT11 sensor for humidity and temperature readings with Raspberry Pi 4. The sensor's principles and applicability in the current world were also studied. In the next tutorial, we'll learn how to interface DS18B20 with Raspberry Pi 4. So, stay tuned. Have a good day.
