When analyzing Arduino's capabilities. It is possible to notice several points that could be better. And its internet connectivity is one of them. To solve this problem, there are modules. and shields 5G USB wifi module and Ethernet, however, these do not agree with the compact nature of the project. That's why, currently, there are microcontroller and prototyping boards like the Esp32.
Throughout this post, the main differences between Arduino. And Esp32 will be explained, as well as the main advantages and disadvantages of their use. How Wi-Fi works and how to implement it together with Esp32 will be explained.
Finally, we will develop a system that will collect the 5G USB wifi module data collect a BMP280 sensor. And send it to a web server that creates us in HTML and which access an IP address provided after Esp32 connects to the local WI-Fi network.
Advantages of Esp32
One of the best platform options to control your project, however, it is not as powerful when compared to other options already on the market today.
However, the Esp32 already comes with a 32-bit processor, 240 MHz of operating frequency, and 4Mb of flash memory, values much higher than those of the Arduino.
At the same time, Arduino's energy consumption is still higher than that of the Esp32, but this is just one among several important ones.
Generally, these modules assist almost every iot device. To make successful connections, we need to rely on durable devices. In this article, we are sharing some basic information for beginners to establish wifi module easily.
One of the most common forms of communication today is the Internet, conveyed via Wi-Fi, which is common for functions ranging from sending data to entertainment. At this point, we will learn a little more about how this technology works and its main features and advantages.
The term is an abbreviation of the term Wireless Fidelity. And refers to “Hi-Fi”. 5G USB wifi module works using radio waves, which are sent, captured. And decoded by the router's antenna. The higher the frequency, the greater the data transmission capacity. The two frequencies for this exchange of information are 2.4GHz and 5GHz.
Inside homes, in IoT devices (Internet of Things, Internet of Things), in household appliances, and even in clothing, inside the so-called “Wearables”.
Inserting Wi-Fi technology into your project will add a lot of value to it. And making its data visualization compatible with virtually all devices that support Wi-Fi. Also, In our demonstration of this article, we will connect the Esp32 to our 5G USB wifi module. However, other possibilities are available, such as the creation of an Esp32 network, making it possible to use the project in other places.
our project
To demonstrate the Wi-Fi technology working together with 5G USB wifi module, we will create a project that will collect data from the sensors and send it to a Web Server connected to our local network.
The focus of the data will be on ambient conditions. And between them, we will collect information related to temperature and atmospheric pressure. Moreover, Temperature and pressure will be measured by a BMP280 module. Also, which is also capable of measuring approximate altitude, however, this data will not be common.
Collection of the data by Esp32 which will store them in variables of types int and float. Inside the code, there will be a variable of type String that will be responsible for storing the HTML code, whose behavior will be analyzed later.
With this address, it will be possible to view our HTML page on all devices connected to the same Wi-Fi network as 5G USB Wi-Fi module. Moreover, it is necessary to follow codes otherwise; you won’t be able to get expected results.
To develop the interface code, the “Microsoft Visual Studio Code” will be common. Which in addition to working as a code editor, is an important tool to be common not only with HTML but with all other languages. See the step-by-step installation of the VS Code below.
How to Install Visual Studio Code
First, go to your browser and search for “vs code” or something that goes back to the editor. At the end of the survey, click on the official VS Code link, as indicated in the image.
Upon entering the page, select the “Download” button to install the latest stable version for Windows. If this is not your operating system, go to the other download options and select your platform.
When opening the installer, the document containing the "Terms of Service" will be displayed; once you accept them, you will be able to proceed with the process.
The 5G USB wifi module is one of the best, most useful, and most practical sensors to be common in IoT applications. This sensor is capable of measuring temperature, atmospheric pressure, and approximate altitude above sea level.
This sensor, as already mentioned, is very practical and has several applications, such as meteorological stations, thermostats, in addition to being able to be common in more ambitious projects such as rockets (for model rockets) and CubeSats.
Conclusion
The inclusion of the 5G USB wifi module in the code is extremely simple, and in our case, only two commands will be common, “read temperature” and “readPressure”, to read the temperature and atmospheric pressure, respectively.
To implement this sensor in your projects you need a library, which can be installed directly from the Arduino IDE, just search for BMP280, in the library manager, and click on the one developed by Adafruit. See the demo below:
