In this blog post, we will delve into the importance of cybersecurity in trading and explore strategies to protect your assets in this digital world.
Trading has come a long way from the days of shouting on the trading floor. With the rise of the internet and sophisticated trading platforms, individuals and institutions can now execute trades from the comfort of their homes or offices. While this has democratized trading and provided countless opportunities, it has also introduced new risks.
Online trading platforms have become a prime target for cybercriminals looking to exploit vulnerabilities and gain unauthorized access to accounts. The motivations behind these attacks can range from financial gain to disruption of financial markets. To safeguard your assets, it is crucial to understand the potential threats and take proactive steps to mitigate them. If you're interested in trading, it's also important to find out more about Binary Options and exercise caution when considering such investment opportunities.
Cyberattacks in the trading world can take various forms, each with its own set of risks. Some of the most common threats include:
Phishing attacks involve tricking individuals into revealing sensitive information, such as login credentials or personal details. Cybercriminals often use emails or fake websites that mimic legitimate trading platforms to deceive traders. Once they have this information, they can gain unauthorized access to accounts and potentially drain them.
Malicious software (malware) and ransomware can infect your computer or platform, giving cybercriminals control over your device or data. Ransomware, in particular, can encrypt your files and demand a ransom for their release, potentially causing significant financial losses.
Insider threats come from within an organization or the platform itself. It could involve employees with malicious intent or individuals who accidentally compromise security. These threats can be challenging to detect and prevent, making them a significant concern for traders.

We know that ICs are made of a combination of logic circuits. The internal structure of these ICs makes the concept of working of the IC clear. If you want to have the details of its structure, you can have a look at the logic diagram of 74LS238 in a positive state:
Figure 3: Logic diagram of 74LS238
If you want to learn this datasheet in detail, you can have a look at the linked article give here:
The basics of the working of this IC in detail are shared with you so that you may know the expected outcomes when using the 74LS238:
This IC consists of three inputs that take only binary information. It means the inputs are only in the form of 0 and 1. The combination of these numbers decodes the output line, where the signals will be high.
The decoding logic of the 74LS238 depends on the internal structure that varies from manufacturer to manufacturer. The logic diagram is shared with you in this tutorial. Different combinations of these logic gates are used to get the required output.
This IC usually consists of AND and NOT gates that process the inputs together and provide the expected output at the output.
The internal structure is responsible for setting one of the eight bits high. This is the basic expectation of this integrated circuit. After processing the input bits, only one output bit is selected where the HIGH signals are sent. All other bits remain low.
There are three enable pins (E1, E2, and E3) that work as the master switch of the decoder. The functionality of each of these is given next:
The E1 and E2 pins work closely with each other and if any one of these is HIGH, the output is always HIGH, no matter what the inputs are.
The pin E3 provides additional control over the output of the decoder. It is an important pin because it acts as the AND gate with three inputs and the overall output is HIGH only when the result of this AND gate combination is set to LOW.
If you want to check the working of this IC then a good option is the proteus simulation. Here, I have created a simple circuit of this IC that will help you understand how the output is generated with 74LS238:

As the name suggests, the basic purpose of using these PCBs is to have the best performance at a higher level of frequency, even in microwaves where other PCBs do not provide the right performance. At such high frequencies, these PCBs show the best performance with minimal loss and distortion. This is the reason why these have applications in extraordinary fields such as aerospace, medical devices, etc.
The basic reason behind the best performance of this PCB is because of its design. From material selection to the fabrication process, these PCBs are designed to keep high frequency in mind. Hence, the nuances of the material are vital to achieving signal integrity with reliable output.
Microwave PCBs are different from traditional PCBs because they are designed for the extraordinary Understanding the features of microwave PCBs will help you a lot to know their basics and applications.
As mentioned before, the basic reason behind the robust performance of these PCBs is because of the material used in their production. These are made with specialized substrate materials that have low dielectric constants and low dissipation factors. Common materials used in their production are:
Polytetrafluoroethylene (PTFE)
FR-4 with PTFE
Ceramic-filled PTFE composites
Here, the basic material is PTFE, whereas FR- and ceramic-filed PTFE are its variants.
As compared to ordinary PCBs, microwave PCBs are employed with thicker copper layers. This not only reduces conductor loss but also contributes to better thermal management. For this, more material is required, and usually, the thickness of microwave PCBs is greater than that of many other types.
One of the most critical features of microwave PCBs is their impedance maintenance. They are designed in such a way that they prevent the phenomenon of signal reflection in microwave signals. Microstrip or stripline configurations are important techniques used during its design, and this ensures efficient power transfer from one point to another in the PCB.
An important feature of this PC is that, during the design process, great care is taken to isolate the component. This includes processes such as strategic component placement and optimized routing so that the circuit has minimal crosstalk.
Another reason why these PCBs provide the best signal integrity is the via design. The following table shows the via design options in the microwave PCBs:

Applications |
High-current applications, high-density designs |
Applications where vias need to be hidden on one side of the PCB, such as for cosmetic reasons or to prevent EMI |
High-density designs, applications where vias need to be hidden on both sides of the PCB |
Another way to maintain the performance of these PCBs is to set the electromagnetic interference (EMI) and electromagnetic compatibility (EMC) compliance in the design. This helps a circuit to adhere to the regulation of electromagnetic standards so that every component in the circuit has the experience of the right EMI and EMC. This not only results in better circuit design but is useful in testing and validation.
As we have discussed so far in this article, microwave PCBs are a specialized type of PCB. these have applications in the areas where PCB tolerance and high sensitivity are required. Here are some major fields where these PCBs are used:
In areas like aerospace and defence, high-performance circuits are extensively used and reliability is an important factor of these circuits. Here, the microwave PCBs are considered one of the best choices. The two most critical applications are discussed below:
For military and aerospace applications, radar systems are the basic devices and these require accurate performance all the time. In these devices, microwave PCBs help to get precise and rapid signal processing.
The electronic warfare system circuity requires a base that may bear the high frequency easily. For such systems, the microwave PCBs are the best choice. As a result, these PCBs help to have the best performance.
The microwave PCBs are the integral base of the systems in the telecommunication fields. These systems are loaded with wireless communication devices and here, usually, the best frequency is in the form of microwaves. Therefore, most of the devices use microwave PCBs to get the best performance.
Communication with the satellite requires a high frequency to communicate through the distance. For this, reliable devices that can bear the high frequency without disturbing the output are required and this is possible with the microwave PCBs.
The sensitive areas like medical imaging devices where accuracy and precision are the life-saving parameters, are always the best pieces of equipment used and microspace PCBs are worth discussing as part of these devices. Here are some medical applications where these PCBs are used:
In medical imaging devices, accuracy is an important factor because of the limitations of the colours. Here, the base of these devices is the microwave PCBs, because ideally, these do not distort the output even at the high frequency. Two important applications in this regard are magnetic resonance imaging (MRI) and computed tomography (CT) scanners.
These PCBs have applications in radio frequency (RF) ablation systems, where they help the expert work on medical treatment with precise control.
In laboratories and scientific research departments where heavy calculations are required and the device runs continuously for a long time, it is better to use microwave PCBs because of their feature to bear high frequencies.

In a number of applications where speed, latency, and light detection are critical, silicon has reached the limits of its capabilities. Global shipments of silicon between 2021 and 2025 are expected to total 17,600 million square inches, according to Statista. It is clear from this report that Moore's law has the potential to last at least until 2025. However, it is also critical to identify a suitable silicon substitute.
Future iterations of the machine will be able to learn from and adapt to its environment thanks to technologies like artificial intelligence. Because of this, more potent and flexible computational processes are required. It is more probable that the production of chips will usher in a new computing revolution. The following are a few possible silicon chip substitutes that could improve computing performance.
University of North Texas, professor Anupama Kaul is setting out on a historic quest to unleash the power of nanomaterials and transform the electronics sector in the cutting-edge field of high-performance computing. Kaul is actively investigating silicon substitutes, tackling issues of national security and inefficiencies with tungsten diselenide as a focus.
Energy inefficiency in the transistor's switching states is currently posing a serious threat to the trillion-dollar silicon electronics sector. According to Kaul, our gadgets, like laptops and iPhones, dissipate a lot of heat. The trillion-dollar electronics industry is powered by silicon, but Moore's Law's limits on transistors scaling and energy inefficiency have put silicon at a critical crossroads.
Kaul's proficiency with two-dimensional layered materials (2DLMs) is evident in this situation. By integrating these materials into chips, she sees a future of computational devices with improved performance and reduced energy consumption. These materials are unique because of their nearly flawless atomic interfaces, which permit electrons to move freely even in nanoscale dimensions without experiencing energy loss or obstructions.
As previously observed, even during the early stages of the development of integrated circuit designs, there were always alternatives to silicon available to engineers and inventors. The tech industry, which spent decades and billions of dollars refining the process before reaching a consensus on silicon, is not in a rush to abandon the process and begin the cycle anew with a different material. Whether used in conjunction with silicon or separately, the search continues for an integrated circuit (IC) that is more compact, quicker, more affordable, and, most importantly, uses less power. Researchers are looking into a number of materials, including black phosphorus, graphene, boron nitride nanosheets, and gallium nitride, as potential alternatives to silicon or methods to improve it to boost its transistor-bearing capacity. They are known as 2-D materials because they are thin, flat sheets that are only one or two atoms thick.
Advanced III-V (gallium-nitride) semiconductor electronics, capable of transforming power into high-voltage transmission and vice versa, will serve as the foundation of our future electrical grid. Innovations in III-V materials, such as bismuthides and antimonides, are opening up new applications in medicine, the military, and other civilian fields. They are also opening up new avenues for communication. The exploration of earth-abundant element combinations to create new semiconductors for low-cost, high-efficiency solar cells is ongoing.
And silicon, that old reliable? Its failure to efficiently harness light does not condemn it to the trash heap of history. By developing "silicon photonics," researchers are revitalizing silicon so that it can handle light more effectively than just moving electrons back and forth. One way is to mix tiny amounts of tin, an additional group IV element, with silicon or germanium. As a result, they have altered properties that improve their ability to both emit and absorb light. That tin inclusion turns out to be a challenging task, similar to many other problems in the field of material science.
As we conclude our semiconductor future study, moving past silicon is possible and necessary. Gallium nitride, graphene, and tungsten diselenide are becoming more popular as the tech industry seeks stronger, more flexible materials. These new materials could revolutionize energy efficiency and processing power. Silicon's photonics evolution shows its versatility.

Choosing a career in engineering presents a myriad of paths, each with its unique challenges and rewards. Among these, specializing in Explosion Protection is a choice that combines technical ingenuity with the responsibility of ensuring safety in hazardous environments.
In this article, we explore the idea of choosing it as a career choice for engineers.
Explosion-Protection refers typically to protecting equipment and systems designed to operate safely in environments where there is a high risk of explosions due to the presence of flammable gases, vapors, or combustible dust.
These machines are engineered to prevent the ignition of surrounding explosive atmospheres, thus playing a key role in industrial safety.
Key industries where this is indispensable include Oil & Gas, where the risk of explosive atmospheres is inherent due to the nature of the products handled.
But also the Chemical industry, known for processing volatile substances and chemicals; and the Pharmaceutical sector, where certain manufacturing processes can create combustible dust.
These machines adhere to strict safety standards, with the ATEX directive in the European Union being a prime leader. This directive ensures that equipment meets essential health and safety requirements, especially in explosive environments.
Originating from the French term "Atmosphères Explosibles", ATEX is the key standard in ensuring safety in environments where explosive atmospheres may occur. An explosive atmosphere in this context refers to a mixture of air and flammable substances in the form of gases, vapors, mists, or dusts, where, after ignition has occurred, combustion spreads to the entire unburned mixture.
The ATEX directive outlines the requirements for equipment and protective systems intended for use in such potentially dangerous settings.
The classification of ATEX is based on zones and equipment groups. This zoning helps in determining the level of protection required for equipment and precautionary measures to be implemented in these areas.
Zone |
Description |
Frequency and Duration of Explosive Atmosphere |
0/20 |
Areas where an explosive atmosphere is continuously present or present for long periods |
Continuous |
1/21 |
Areas where an explosive atmosphere is likely to occur in normal operation |
Occasional |
2/22 |
Areas where an explosive atmosphere is not likely to occur in normal operation and, if it occurs, will exist for a short period only |
Infrequent |
Compliance with these ATEX zone requirements is not just a legal obligation but a fundamental aspect of ensuring the safety and well-being of personnel and the integrity of facilities in these high-risk areas.
ATEX equipment groups are categories also defines in the European Union's ATEX directives to classify equipment intended for use in potentially explosive atmospheres based on the environment where the equipment will be used. There are two main ATEX equipment groups:
Group |
Environment |
Category |
Description |
I |
Underground mines and surface installations at risk from firedamp and/or combustible dust |
M1 |
Equipment must provide very high protection and remain functional even during an explosive atmosphere. |
M2 |
Equipment must be designed to cease operation in the presence of an explosive atmosphere. |
||
II |
Surface industries at risk from explosive atmospheres |
1 (1G/1D) |
Very high level of protection for areas where an explosive atmosphere is continuously present or present for long periods. |
2 (2G/2D) |
High level of protection for areas where an explosive atmosphere is likely to occur in normal operation. |
||
3 (3G/3D) |
Normal level of protection for areas where an explosive atmosphere is not likely to occur, and if it does, will exist only for a short time. |
The categorization and grouping help manufacturers and operators ensure that the correct type of equipment with the appropriate level of protection is used in environments with potentially explosive atmospheres, thereby reducing the risk of ignition and ensuring safety and compliance with regulations.
Example: HVAC/AC Systems
If used in a continuously hazardous area (like a Zone 0 or Zone 20), it might need to meet Category 1 requirements (1G/1D). If the for areas with a low likelihood of explosive atmospheres (like a Zone 2 or Zone 22), the hazardous location air conditioner would typically meet Category 3 requirements (3G/3D).
So the HVAC manufacturers must conduct thorough testing and certification processes to ensure their equipment complies with ATEX directives for the intended usage zone.
Subsequently, buyers should always consult the equipment's certification documentation to verify its ATEX group and category before using it in hazardous areas.
Now to circle back to our main topic. How do Engineers fit into this very specific niche?

The field of industrial ultrasonic testing has a lot of useful tools. At the top of the list is an ultrasonic thickness gauge, the best instrument for non-destructive investigation. It has been in use since 1967, and has only gotten better with time.
Ultrasonic thickness gauges use ultrasonic waves to determine the thickness of materials. This is one of the top reasons it comes recommended as an NDT measurement tool by Coltraco Ultrasonics . Without the proper tools, nondestructive testing techniques would be replaced with traditional analysis methods. Altering materials for an evaluation isn’t exactly the best way to use a company’s resources, and can even change the timeline for starting a project. With a UTG, the investigator can collect all of the necessary data without having a negative impact on the project. This is not only cost-effective but less time-consuming than the previous testing methods.
The three main types of traditional thickness gauges are material, coating and wire/sheet. These measuring instruments are the foundation that paved the way for its UTG counterpart. With the built-in ultrasonic transducer, a pulse sound wave is emitted into the material. As it pulses, information is sent back to the transducer that automatically calculates the return time for an accurate measurement. You only need access to one side of the material, so it’s handy to have in limited or tight spaces. When there is a lot of ground to cover, a UTG can speed things up by a considerable amount.
A protective coating can provide a false sense of security that shows a healthy outside while hiding major damage on the inside. You can’t eyeball a modern ship to judge its hull integrity. Even with careful inspection of its exterior health, a lot of small details can slip through the cracks. For an inspector to do their due diligence, it becomes essential to get accurate data without having to remove this coating . With a UTG, you can analyze the hull to find corrosion spots that would escape the eye test. Since a UTG ignores the irrelevant protective coating, the actual data used to determine the integrity will always be up to date. After multiple echoes from the tool, you’ll be able to make the necessary adjustments for present or future maintenance.
It is well documented how easy it is to measure pipe and tube wall thickness with a UTG. Pipes in particular are mazelike and can lead to inaccessible areas by normal means. You don’t need full accessibility to the pipes accessible ends to get a good measurement. This alone will prevent a lot of incorrect data that comes from estimates. It will also prevent you from having to shut down or cut pipes for a good thickness measurement. Something that isn’t mentioned enough about this method is the pain it can be when a current process relies on something that needs to be measured. With a nondestructive inspection, the fear of shutting an entire department for a test is no longer an issue.
Long-term corrosion is a problem that the industry is always looking to resolve. Up to date maintenance is still the answer, but that comes with a heavy reliance on monitoring possible corrosion. Weathering steel structures are pretty easy to maintain when you stay on top of your evaluations. In order to make the process painless for everyone involved, a UTG is used to measure the residual steel thickness. This is all done without the need for a couplant to help with the transmission of ultrasonic energy. The data returned measures both the original steel thickness and the thickness of the rust layer. For companies that have missed a few checks, a UTG can provide a ton of useful information for maintenance.
The ultrasonic waves work with metals, plastics, composites, ceramic lass, fiberglass and more. Things get even more interesting when you factor in how well it works with coatings, rust and other surface materials. For advanced testing, rubber and liquid level measurements have proven to be quite successful when there is trouble accessing both sides of the material. This versatility in analyzing data makes it essential since it covers pretty much all of the important materials used in industrial maintenance and inspection. With safety and quality standards on the rise, the use of a UTG will become mandatory.
In order for everything to work properly, the device needs to be calibrated. This is a quick task for a UTG since it depends on the speed of sound energy bouncing off of the tested material. By getting the echo timing precise, you guarantee the best accuracy when measuring. Gauge calibration for specific materials can be recalled to speed up the entire process. New calibrations should be set as necessary, especially when the testing material changes temperature. For critical applications, it is a small price to pay to get the readings right. A UTG is still an incredible tool, but it is only as good as the effort put into its calibrations.
The sinking of the Erika was an event that happened on December 1999. A Maltese tanker broke in half and spilled close to 19,800 tons of oil by the coast of Brittany France. Bad maintenance led to corrosion, and that corrosion was magnified by traveling in severe weather. It is a good example of a tanker that passed the eye test but could have been saved by the readings of an ultrasonic thickness gauge. Multiple stories caused by this type of corrosion occurs in several industries per year. As the disasters rise, inspections are ramping up their protocols and making safety a top priority.
When you look at all of the advantages of an NDT measurement tool, it would be catastrophic to go without it. An ultrasonic thickness gauge is a standard that won’t be bested anytime soon. For inspection, induction and measurement processes, this is the only way to go.

Welcome to the next tutorial in our Raspberry Pi 4 programming course. In the previous tutorial, we learned how to automate your home with a Raspberry Pi and Bluetooth Low Energy. We found that using a Raspberry Pi 4 and Bluetooth Low Energy (BLE), users may command their household appliances from their smartphone or a web interface, and the Pi 4 will carry out the commands. This allows for a versatile and adaptable method of managing lights, thermostats, and smart plugs.
However, this Internet of Things (IoT) project aims to create a real-time Raspberry Pi weather station that displays the current humidity, temperature, and pressure values via an LCD and an online server. With this arrangement, you can track the local climate from any location in the globe over the internet and see what the weather is like right now and how it has changed over time via graphs.
The original Weather Station equipment is a HAT for the Pi that 4 incorporates several sensors for measuring the weather. It is intended for classroom use, where students can use the included materials to build their weather stations. In terms of both electronics and code, this is an advanced project. So before making any purchases, ensure you've read the entire project.
A Raspberry Pi
WiFi dongle
A BME280 pressure, temperature, and humidity sensor
A DS18B20 digital thermal probe
Two 4.7 KOhm resistors
5mm-pitch PCB mount screw terminal blocks
A breadboard, jumper wires
An anemometer, wind vane, and rain gauge
Two RJ11 breakout boards (optional)
An MCP3008 analog-to-digital converter integrated circuit
Weatherproof enclosures
Installation for measuring and recording atmospheric conditions and environmental variables in a specific area. Starting with a breadboard and some jumper wires, you'll design and construct a working model of a weather station. After you've gotten the prototype up and running and tested, you can create a more permanent version for use in the real world.
This weather monitoring system runs on the Oracle Raspberry Pi. While installation is not required, you will use Python's many valuable tools. Start a new Terminal window and enter:
git clone https://github.com/RaspberryPiFoundation/weather-station
The BME280 Python library:
sudo pip3 install RPi.bme280
MariaDB is a database server software that:
sudo apt-get install -y mariadb-server mariadb-client libmariadbclient-dev
Sudo pip3 install mysqlclient
Your weather station will require an internet connection to transmit data to a location where it can be seen and analyzed. WiFi is the most convenient option; however, an Ethernet connection can be used if necessary.
Compared to the "through-hole" connections used in many other digital manufacturing kits, stripboard connectors can be more challenging to solder. However, the plated through-hole contacts on the prototyping HATs for the Raspberry Pi make them much more convenient.
If you have an Adafruit Perma-Proto HAT Kit, you can build a weather station like the one in the following circuit schematic. If you're using nonstandard parts, you have some flexibility in arranging everything.
Female headers represent the six pins found on the two RJ11 breakout boards so as not to obstruct the view.
Using this diagram to construct a circuit on a breadboard will call for a slightly unconventional method of thought. As the PTH connections are continuous throughout the board, you can route and join wires and components from either side.
With two 2-pin male connectors, as seen in the image above, the BME280 sensor can be easily attached to various devices. The sensor can then be placed in a dedicated housing, simplifying assembly. But, after passing the wires from the sensor through the grommets or glands designed to keep water out, you could solder them straight to the HAT.
You should add a weather sensor to the board and test it individually before moving on to the next stage.
Initiate by soldering the 40-pin header to the Adafruit board.
Connect the SCL & SDA pins in the upper left and the 3V & GND pins using two 2-pin male connectors you have soldered in place.
To use the BME280 sensor, attach the HAT to the Pi and plug in the sensor's pins.
Power up the Pi and verify the BME280 sensor is functional by running the bme280 sensor.py program you created.
The DS18B20 probe's wires should be connected next. Again, use screw terminals on the breadboard. If you look closely, you'll see that one of the RJ11 breakout boards has some spare pins you may use on the proto-board. While the rain gauge only uses the connector's two center pins, the two on either side are available as screw terminals, allowing you to economize on floor space cleverly.
Turn off the power and take off the HAT from the Pi.
Install a resistor with 4.7K ohms of resistance in the bottom section by soldering it there. If possible, seat the resistor so that it is flush with the top of the Adafruit board and not protruding upwards; this will allow your RJ11 breakout board to rest immediately above it.
Make two more wire connections to the GND rail at the bottom.
Using longer cables, attach the GPIO pin breakout connectors (GPIO 4, 6) to the 3V rail. Again, it would be best if you positioned these at the base of the RJ11 breakout board. Since the HAT is hollow at its base, the wires can be soldered through from underneath. Either side of the HAT can be used as long as the appropriate holes are joined.
A smart option is to move the 3V rail connection to the back of the board, as doing so will avoid it going through a "busy" area on the top.
Get the RJ11 breakout board ready. It's essential to be careful around the sharp edges of the pre-soldered components on these breakout boards. Carefully snip off the protruding bits of solder using side cutters to prevent the peaks from generating shorts when soldered into the Adafruit board. Wrapping a thin piece of insulating tape around them is also a good idea for added protection.
Male pins required to connect to an Adafruit board are not included with some models of the smaller panels. These may first require soldering onto the breakout board. When soldering pins onto the Adafruit board, make sure the shorter end of the pin is touching the board.
Be sure the RJ11 breakout board's pins are inserted into their corresponding holes on the Adafruit board before soldering it. Avoid getting the RJ11 socket too hot, or the plastic will melt. When the HAT is attached to the Raspberry Pi, the long pins on the breakout board will connect to the video output via the Pi's HDMI connector. For this reason, you should either shorten them or insulate the HDMI port's top to avoid a short.
The DS18B20 sensor must be connected to the breakout board's screw terminals, as shown below.
To reattach the HAT to the Pi, you must take great care. First, ensure the Adafruit board's soldered connections aren't touching any of the Pi's top components before turning the power on. If they are, the relevant pins or wires should be shortened.
Start the ds18b20 therm.py script on your Pi after powering it on and testing the DS18B20 sensor.
Hook up the RJ11 cable from your HAT to the rain gauge.
Put your custom rainfall.py routines to the test and see if the rain gauge measures precipitation.
Currently, the MCP3008 ADC must be integrated. The IC could be soldered directly into the Adafruit board, but a DIP/DIL IC socket would be preferable. This lessens the potential for IC damage and facilitates future component swapping.
Take out the HAT & solder the connector to the Adafruit board, where the MCP3008 IC is depicted.
Connect the IC and the additional RJ11 breakout board to the power supply and ground using five short lengths of wire.
Add the remaining GPIO connections using the longer wire strips. You can route these connections on the top or bottom of the board, though it may be more difficult to solder the GPIO pins near the black plastic of the female connector on the bottom. Wind vane wiring requires just two more wires.
The other 4.7K ohm resistor must be soldered in place.
Next, connect the other RJ11 breakout board, ensuring no short circuits are created by the board's pins, which can be particularly dangerous if they are sharp or excessively long.
Place the MP3008 IC carefully into the socket. You should gently fold the legs inward before they fit into the socket without getting squished by the bulk of the chip.
It's time to put the HAT back on the Pi. Make sure that the Adafruit board's soldered connections are not making contact with any of the Pi's uppermost components. Cut off any excess wires or pins.
Connect the RJ11 cable from the wind sensors and run the wind direction byo.py and wind.py tests you created to see how well they work.
The HAT you made for the weather should now be completely functional. So check it out using the final, fully functioning version of the application we'll cover in this tutorial.
Any Weather Station must include sensors for measuring relative humidity, temperature, and barometric pressure.
We employed a DHT11 temperature/humidity sensor and a BM180 pressure sensor module. The LCD screen on this Thermometer with a Celsius scale and Humidity meter with a percentage scale also shows the current barometric pressure in millibars or hPa (hectopascal). All of this information is uploaded to the ThingSpeak server, which can be viewed in real-time from any location with an internet connection. Towards the end of this guide, you'll find a demonstration video and a Python program.
Digitally measuring temperature, humidity, and barometric pressure, the BME280 sensor is an all-purpose instrument. Several breakout boards from well-known brands, like Adafruit and SparkFun, feature it. The Adafruit package is assumed for this tutorial; however, the procedures should translate well to other distributions. First, ensure you're using the correct I2C address; in the code below, we're using 0x77, the address for Adafruit models. However, other versions may use a different address (0x76).
As illustrated in the above diagram, connect the sensor to the Pi.
The extra pins (such as SDO or CSB) on some breakout boards are rarely used but are available for those who want them.
Please make a new Python file and save it in the /home/username/weather-station/bme280 sensor.py directory. Then, substitute your Raspberry Pi username for the username in the following code.
import bme280
import smbus2
from time import sleep
port = 1
address = 0x77 # Adafruit BME280 address. Other BME280s may be different
bus = smbus2.SMBus(port)
bme280.load_calibration_params(bus,address)
while True:
bme280_data = bme280.sample(bus,address)
humidity = bme280_data.humidity
pressure = bme280_data.pressure
ambient_temperature = bme280_data.temperature
print(humidity, pressure, ambient_temperature)
sleep(1)
Now put the code to the test by letting out a big sigh upon the sensor while the program is running. Humidity readings (and perhaps temperature readings) ought to rise. You can quit the Python shell by pressing ctrl+c after testing the code. If the sensor is recording reasonable values, you can adapt the software to be utilized as a part of the more extensive weather station system. Change the while True loop to a call to a read all() function that sequentially returns the current humidity, pressure, and temperature.
When it's cold outside, the BME280 will read the air temperature, which may be much higher than the ground temperature. Indicating the presence of ice or frost in the winter using a thermal probe inserted into the soil is an excellent supplement to standard temperature measurement. The Oracle Pi 4 Weather Station utilizes the Dallas DS18B20 temp sensor in several configurations, including a waterproof heat probe version.
Since the DS18B20 typically only has three bare wires, prototyping and testing the sensor is a breeze with PCB mount screw connector blocks that can be connected to breadboards. Connect the DS18B20 to the circuit as depicted in the image. Note that you're connecting the breadboard's 3.3 Volt and Ground wires along the board's edge. They will be necessary for expanding the circuit to accommodate more sensors.
Open the file /boot/config.txt:
sudo nano /boot/config.txt
Edit it by:
Then open /etc/modules.
sudo nano /etc/modules
Include the following lines at the end of the document:
w1-gpio
w1-therm
Now restart the Raspberry Pi. Then load up ds18b20 therm.py from /home/pi/weather-station/ in IDLE. The Python prompt should now display the current temperature.
Submerge the probe in ice water and restart the process. The newly reported temperature should be lower if you weren't already operating in a freezing room.
The Figaro TGS2600 sensor was initially included in the Oracle Raspberry Pi 4 Weather Station package. We've had good luck with the first set of devices integrated into the Station HAT, but the most recent devices we've tried have proven difficult to adjust and have given us conflicting results. While they work well for monitoring broad changes in atmospheric gases, their specific application in a personal weather station has yet to be recommended. As soon as we settle on a budget air quality monitor, we'll update this article with our findings.
All the electronics you've employed as sensors until now are passive; they observe and record data. However, active machines directly interacting with the environment must measure rainfall and wind speed/direction.
The initial Oracle Station kit used standard components in many home weather stations, such as wind and rain sensors. For their durability and dependability, these sensors are highly recommended. The data sheet has more info about the sensors' dimensions and build quality.
The RJ11 connectors that come standard on these sensors (they resemble a regular telephone jack) are solid and unlikely to become accidentally dislodged, ensuring that your weather station continues to function despite the wind.
There are three ways to hook them up to your Pi:
You can use screw terminals or solder to join the wires after severing the male RJ11 connectors.
Utilize female RJ11 connectors, which are challenging to work with on breadboards but can make for a rock-solid connection when soldered to a PCB for use in a fixed weather station.
While RJ11 breakout boards are great for prototyping, their larger counterparts may need to be more practical for permanent installations.
The smaller ones typically have solderable pins that can be connected to a stripboard or a prototype HAT. These smaller breakout boards will be used in the following assembly instructions to build a permanent hardware solution.
The anemometer's three arms capture the wind, culminating in scoops and rotation. The first Oracle Weather Stations employed anemometers with a small magnet connected to the underside to measure wind speed.
This illustrates a reed switch, a clever piece of electronics triggered by the magnet at two rotation points.
In the presence of a magnet, the reed switch's internal metal contacts will contact one another. This switch's electronic operation is identical to a button attached to the Raspberry Pi; as the anemometer spins, the magnet briefly closes the circuit formed by the reed switch. Because of this, the rate at which the anemometer spins can be determined by counting the signals it receives from the reed switch.
The reed switch generates a signal that may be picked up on a GPIO pin whenever it is actuated. The sensor will send out two discernible signals for every entire rotation of the anemometer. You can figure out how fast the wind blows by tracking and timing these signals.
Python provides a plethora of options for achieving this. For example, a button-like sensor can be counted using the gpiozero library. The gpiozero library, for instance, can be used to count the number of times a sensor was "pressed" to simulate its use as a button.
It's common for consumer anemometers to have two cables. Pair them up by connecting one to GPIO 5 and another to the ground. The anemometer connects to pins 3 and 4 on standard RJ11 breakout boards in the cable's center.
After you connect the anemometer, your connection should resemble this:
Start IDLE, make a new Python file named "wind.py," and save it to the /home/pi/weather-station directory. Insert the code below to assign GPIO5 to the Button class and use GPIO0's Button methods. Create a counter named wind count to keep track of how many times the wind has shifted directions.
from gpiozero import Button
wind_speed_sensor = Button(5)
wind_count = 0
Now you can set a function to be executed anytime a turn of the anemometer triggers the pin.
def spin():
global wind_count
wind_count = wind_count + 1
print("spin" + str(wind_count))
wind_speed_sensor.when_pressed = spin
You can now exit the editor and run the code. The anemometer's accuracy can be checked by manually rotating its arms. You should be able to see your code being executed in the Python shell, with the count variable increasing by two with each revolution.
The anemometer's signals can now be counted, allowing you to determine the wind speed.
As the anemometer generates two signals per rotation, you may determine the total number of sensor revolutions by dividing the total number of signals by two. The wind speed can therefore be determined from this:
Speed = distance / time
The distance covered in a given time period is a necessary input when attempting to determine velocity. Time is easily quantified by counting the occurrences of a signal over some predetermined interval, say five seconds.
One cup will travel a distance according to the product of the number of revolutions times the radius of the circle:
Speed = (rotations * circumference) / time
If you know a circle's diameter or radius, you can figure out the circumference.
To determine the diameter of the circle produced by the anemometer, measure the radius of the cups. Knowing the radius, you can calculate the circumference using the equation 2 * pi * radius. Keeping in mind that a complete rotation produces two signals, you will need to decrease the overall amount of signals detected by half:
Speed = ((signals/2) * (2 * pi * radius)) / time
Here are some code snippets based on the radius of 9.0cm, which is the size suggested for the anemometers used in the first Oracle Weather Station. If your anemometer's dimensions differ, make sure you adjust this value.
This formula can be used with the maths library in Python. If you took 17 readings from your anemometer for 5 seconds, you could figure out how fast the wind was blowing in this way:
import math
radius_cm = 9.0
wind_interval = 5
wind_count = 17
circumference_cm = (2 * math.pi) * radius_cm
rotations = count / 2.0
dist_cm = circumference_cm * rotations
speed = dist_cm / wind_interval
print(speed)
Remove the line from the spin method that prints it out to prevent the wind count value from being displayed.
Now you can use this equation to adjust your wind.py program so that it also determines the wind speed in cm/s).
The code currently uses a unit of measure equivalent to centimeters per second for the wind speed. Unfortunately, this could be more helpful; (km/h) is a more useful measurement.
Adjust your program to give wind speeds in kilometers per hour.
An anemometer's accuracy can be verified using the information provided in the device's specification, which is often found in the manual. For example, according to the specifications for the suggested anemometers, 2.4 kilometers per hour is equivalent to one spin per second. Therefore, the same 2.4 km/h wind velocity should result from five rotations (ten signals) in five seconds.
Spin the anemometer five times in the first 5 secs after your program has started. What exactly is the stated wind speed?
You'll likely discover the value is off from what was expected. The anemometer factor is to blame for this discrepancy; it is the amount of wind energy that is dissipated whenever the arms rotate. An adjustment factor can be multiplied by the program's output to account for this.
Anemometers with this rating are 1.18 for the recommended models.
You need to change the final line of your calculate speed function so that it multiplies your speed in kilometers per hour by 1.18.
Correctly displaying the output in the appropriate units requires modifying the final print line of your code.
If you re-run the code, you will likely get a speed estimate closer to 2,4 kilometers per hour.
It will be helpful to reset the wind count variable to zero when putting the weather station together; therefore, implement that functionality now.
def reset_wind():
global wind_count
wind_count = 0
The average and maximum wind speeds and any significant wind gusts are typically included in weather reports and forecasts. Whenever the wind is present, there is always the potential for a temporary but significant increase in wind speed, known as a gust. As the wind picks up momentum, it becomes easier to detect gusts. This occurs because the wind's force rapidly rises with increasing wind speed.
The inability of the air to move at a consistent pace along the ground is the usual source of gusts. Because of differences in surface friction caused by obstacles like plants, buildings, and elevation variations, wind speeds will vary across the landscape. This effect is more noticeable in lower-altitude air than in higher-altitude air. Because of this, gusts are produced as the wind flows more erratically along the ground. It takes fewer than 20 seconds for the average wind gust to pass.
With a fully functional weather station, you may measure the average wind speed over time, and the maximum speed experienced during that period (the gust). To do this, one can continuously take five-second readings of the wind speed, storing them in a buffer for later processing once every several minutes. In Python, lists are the appropriate data format for this task.
The wind.py file can be found in the /home/pi/weather-station directory; open it in IDLE.
Import the statistics libraries with a single line added at the very beginning.
import statistics
Next, just beneath the import lines, add the line below, which defines an empty list named store speeds:
store_speeds = []
Now, edit the while True loop to include a new one that continuously collects wind speed data and appends it to the previous tally. Then, statistics can be used to determine the average speed from the store speeds data set.
while True:
start_time = time.time()
while time.time() - start_time <= wind_interval:
reset_wind()
time.sleep(wind_interval)
final_speed = calculate_speed(wind_interval)
store_speeds.append(final_speed)
wind_gust = max(store_speeds)
wind_speed = statistics.mean(store_speeds)
print(wind_speed, wind_gust)
Take note that time is being used. Start by using the time() to generate a variable named start time, and then use the while loop's inner check condition to see if the current time has progressed by more than the wind interval seconds.
Start executing your program. Just blow into the anemometer or manually spin it and observe the results.
Once you stop spinning, the anemometer's average speed will decrease while the second measurement will remain constant (because this is the highest gust produced). For the next steps, please follow our next tutorial on how to build an IOT-based weather station.
In this post, we learned the basics of using a Raspberry Pi as the basis for an Internet of Things-based weather station. In the subsequent session, we will learn how to develop the Python code that will bring our weather station circuit design to life.
