With the help of an ESP32 and an anemometer, we will demonstrate how to read wind speed from a TFT display. The project makes use of an integrated board that has a 3.5-inch touchscreen display, an ESP32-WROVER Module, and an OV2640 camera that has a built-in resolution of 2 million pixels. We are going to connect the Anemometer Sensor to the analog pin on the ESP32 in an external location. An instrument known as an anemometer is used to determine both the speed and the direction of the wind. The Adafruit anemometer is the one that serves as the sensor for this particular anemometer. The Adafruit anemometer has the ability to measure wind speeds of up to 70 meters per second, which is equivalent to 156 miles per hour. An ILI9488 TFT LCD

Driver is utilized in the construction of the 3.5-inch TFT Touch Screen Display. The resolution of the screen is 320 by 480. There are a number of external pins on the ESP32 display that can be used to connect it to sensors or actuators. Because of this, they are appropriate for a wide variety of Internet of Things applications. Now that we have the Anemometer Sensor, let's take a look at how we can utilize it in conjunction with the ESP32 TFT Display to create a stunningly dynamic widget. Along with the severity of the warning, the wind speed will be displayed on the TFT Display in miles per hour.

The incorporation of all of these elements results in the creation of an ideal platform for a variety of ESP32 applications and projects.

The TFT LCD driver is essentially an ILI9488, and it measures 3.5 inches in size and has a screen resolution of 320 by 480 pixels. The ILI9488 LCD communicates with the ESP32 microcontroller via SPI (Serial Peripheral Interface). Making the display smooth enough for videos may require the SPI main clock to be increased to between 60M and 80M. You are free to make use of any and all of these pins on the breakout connections while the camera is not being utilized. After that, you may utilize the ESP32 display for any Internet of Things application you want by connecting it to sensors or modules. Programming in Arduino and MicroPython are both supported by the ESP32 microcontroller. A micro-SD Card slot is provided on the board for the purpose of adding an external SD Card. Files and pictures can be saved to the SD Card and accessed whenever necessary. There is a USB Type-C port available, which functions as a USB to UART converter and can be used for ESP32 programming. You can directly upload the code to the board by connecting a Type-C data connection to it and then following the on-screen instructions.

Adafruit Anemometer Sensor The Adafruit Anemometer Sensor is a Three-cup type anemometer that has the potential to measure wind speeds of up to 70 meters per second (156 miles per hour). It is made up of three different parts: the circuit module, the wind cup, and the shell.

A length of wires with three cores and three connections are included with the sensor in the package. A brown wire for power, which can be anywhere from 7-24 volts DC, a third blue wire that offers measurements via analog voltage, and a black wire for power and signal ground. The analog voltage that is output will range from 0.4V (when there is no wind) up to 2.0V (when there is 32.4m/s of wind).

Voltage Required: 7-24v DC 0.4V to 2V as the output range The range of testing is from 0.5 m/s to 50 m/s. Beginning wind speed: 0.2 meters per second Resolution: 0.1m/s Worst case scenario for accuracy 1 meter/s The maximum wind speed was 70 meters per second.

Pin details: Power is provided by the brown wire at pin 1, ground is provided by the black wire at pin 2, and signal is provided at pin 3. (Blue wire) Connections for the Hardware of the ESP32 TFT Display with the Anemometer Because the TFT Touch Display and ESP32-Wrover Module are already wired to the PCB on the inside, the only component we need is the Anemometer Sensor.

Connect the external 9V and GND to the VCC and GND pins of the anemometer sensor. Establish a connection between the GND terminals of the external power source and the GND terminals of the ESP32. In a similar fashion, connect the input pin for the anemometer to GPIO35 on the ESP32. Installing TFT eSPI Library to Arduino IDE

This is a TFT graphics library for Arduino processors, optimized for performance for STM32, ESP8266, and ESP32. The library is formatted specifically for use with 32-bit processors. The "Four wire" SPI and 8 bit parallel interfaces are both supported by it. Some TFT displays are supported by the library, and drivers are provided for them (ILI9163, ILI9225, ILI9341, ILI9488, ST7735, etc.). Measure Wind Speed with Anemometer on ESP32 TFT Display Following the successful upload of the code, the TFT Display will immediately begin displaying the Wind Speed data using an attractive widget. In order to cause the warning signal to appear on the display, you can manually rotate the cup of the anemometer at a high speed. This is how you can measure the wind speed using the ESP32 and the Anemometer Sensor, and then display the wind speed value using the beautiful widget on the TFT Display.
