DHT22 Temperature and Humidity Sensor Module

Description 

The DHT22 is a digital sensor used to measure temperature and humidity with higher accuracy and a wider measurement range than the DHT11.It provides calibrated readings and sends the data to a microcontroller through a single digital output pin. 

The sensor measures the surrounding temperature and humidity, processes the data internally, and transmits the readings as a digital signal. This makes it easy to interface with Arduino, ESP32, Raspberry Pi, and other microcontroller platforms. 

The module has three pins: VCC, DATA, and GND. Only one data pin is required for communication, helping reduce wiring and simplify project design. 

The DHT22 is commonly used in weather stations, environmental monitoring systems, greenhouse monitoring, and home automation projects.
