How do I interface with the DHT22 Temperature and Humidity Sensor Module?

Wednesday, June 21, 2023 Category:

To interface with the DHT22 Temperature and Humidity Sensor Module, you’ll need a microcontroller or development board capable of digital input/output (I/O) and a compatible library. Here are the general steps involved:

Connect the VCC pin of the DHT22 module to the 3.3V or 5V power supply of your microcontroller or development board.
Connect the GND pin of the DHT22 module to the ground (GND) pin of your microcontroller or development board.
Connect the data pin of the DHT22 module to a digital input/output (I/O) pin of your microcontroller or development board.
Install the appropriate library for the DHT22 sensor module in your programming environment.
Use the library functions to read the temperature and humidity values from the sensor and process them as needed in your code.
