As we are moving towards and becoming the tech generation, it's exciting to know how IoT Application Development has a huge Market Potential - wondering how it is possible? Let us tell you more.
Do You Know?
Let us tell you a fun fact. Worldwide there are about 9 billion Internet of Things (IoT) devices connected in 2020, which ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn about the ESP-NOW protocol and how to communicate data between two ESP modules through ESP-NOW protocol and that is too without Wi-Fi connectivity.
What is ESP-NOW Protocol?
Fig. 1: ESP-NOW Protocol
ESP–NOW is a connectionless communication protocol that is used for sharing small data packets between two ESP boards. This protocol is developed by Espressif.
Features of ESP-NOW Protocol:
It is a low-power wireless protocol, which makes two or more ESP devices communicate directly with each other without using Wi-Fi.
ESP-NOW protocol does not require a handshake for establishing a connection but, they require pairing and once the devices are paired they can exchang ...
Hello friends, I hope you all are doing great. Welcome to the 3rd lecture of Section 5(ESP32 Sensors) in the ESP32 Programming Series. We have already discussed the two built-in ESP32 sensors i.e. Hall Effect Sensor and Capacitive Touch Sensor. Today, we are going to discuss the 3rd and final built-in ESP32 sensor i.e. Internal Temperature Sensor.
ESP32 Internal Temperature Sensor is used to calculate the temperature of the ESP32 core. So, we can't use it to measure the ambient temperature (the temperature of the atmosphere), for that, we need to use embedded temperature sensors i.e. DS18B20, DHT11, BMP280 etc. We will first discuss the basics of this Internal Temperature Sensor and then will design a code to monitor the change in temperature by changing the frequency of the ESP32 CPU.

Hello readers, I hope you all are doing great. In our previous tutorial, we learned SMTP server and how to implement an SMTP server for sending emails with ESP32. In the previous tutorial, we also demonstrated some examples like sharing raw text, HTML text, images and text files.
So, at the transmitter end, we are using the SMTP server.
But, what about the receiver end?
At the receiver end, we use another protocol called IMAP (or Internet Message Access Protocol) and POP3 (Post office Protocol V3) for receiving the emails.
Fig. IMAP and SMTP
What is IMAP Protocol and How does it Work?
IMAP is an application layer (TCP/IP) protocol that is used at the receiver end to receive emails from SMTP server or mail server. IMAP follows the client/server mo ...
The transportation and logistics industry suffered from the impact of the pandemic. The disruptions in supply chains caused massive losses in businesses. Its spillovers extended to those relying on freight and delivery. But as the restrictions started to ease, its recovery followed instantly.
In 2021, supply chains benefited from the boom in e-commerce as online buyers reached 2.14 billion. Given the massive influx of customers, businesses had to scale up their operations. The challenge now is to improve efficiency and ensure the delivery of goods and services. It has become more challenging for companies to monitor every movement, especially logistics.
Fortunately, service dispatch software can make things easier and safer. Tracking vehicles and ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to send an email using ESP32 module. We will also learn to send text files, images or some sensor readings using the SMTP server using the ESP32 module.
In IoT (Internet of things), there are various applications where we need to send emails carrying information like sending some sensor readings, altering emails, images, text files and much more.
What is SMTP?
SMTP or simple mail transfer protocol is an internet standard for sending and receiving electronic mail (or email) where an SMTP server receives emails from the email client.
SMTP is also used for setting communication between servers.
Various email providers like Gmail, Hotmail, Yahoo, etc. have unique SMTP ...
Hello friends! We hope you are very well! Today we are here for complementing our knowledge with one of the most important topics in PLC programming and practice its implementation in PLC ladder logic programming. Our topic today is about counters which help us to know the production size at any time, the repetition of specific tasks and events. Many real-life situation problems need counter like garage capacity should be tracked by using counters to report how many cars are inside and if there is room for incoming cars or it's full. Another critical problem is to count the repetitive tasks and events in manufacturing. Furthermore, counting products and pieces for taking an action like performing maintenance, stop operation, turn over to next prod ...
Hello friends! I hope you are doing very well, today we have a very crucial topic which is “timers”. Yes! Exactly like what comes to your mind. For running equipment i.e. motor at a specific time and/or for some amount of time we need timers. Timers are used even before PLC in classic or relay logic conventional control. However, there is a big difference between capabilities and limitations between using physical timers in classic or old fashion relay logic and using software timers in PLC. By completing this article you will be able to know what are timers and their types and applications. In addition, we are going to show off how to use timers in ladder logic programming with examples.
What are timers used for in industrial applications?
Well! ...
Hi friends! I hope you are doing well! Today we are going to learn and practice a new topic which is a very crucial technique in plc programming. the topic is called “latching”. We mean by Latching to keep the output running starting from the instance of giving a kick-off command until we hit a command to stop running of the motor. Imagine my friends, operator wants to start a motor by hitting a start push button and want the motor to keep running and leave and go for doing another task or job. And then it keeps running until the operator wants to stop it. The problem here is that, once the operator releases his hand away from the push button, the motor automatically stopped and that is not like what the operator wants to do with the motor. To clear the problem that we are going to solve, ...
Over the past century, dental care has remained a relatively rigid area of healthcare. However, the accelerated digitization of the past two decades has seen the sector rapidly adopt mainstream technologies, with the advancement taking a seemingly steeper trajectory by the day. We looked at some of the new technologies making their way into dentistry and came up with this list of what we reckon will rock the world of dental care for years to come:
3D prosthesis printing
3D printing is getting deeper and deeper into medicine. Many companies use 3D printing machines to create prosthetics to replace missing body parts. Although subtractive manufacturing still heavily dominates dentistry, the general projection is that 3D printing will eventually tak ...
