The DHT22 Digital Temperature and Humidity Sensor Module is a digital environmental sensor designed to provide accurate measurements of both temperature and relative humidity through a simple single-wire digital interface.
The DHT22 can measure temperatures from approximately -40°C to +80°C and relative humidity from 0–100% RH, making it suitable for applications that require a wider operating range than the DHT11. The sensor provides digital data directly, eliminating the need for an external analog-to-digital converter.
With its simple interface and easy integration, the DHT22 is commonly used with Arduino, ESP32, STM32, Raspberry Pi, and other microcontroller platforms. It is suitable for environmental monitoring, weather stations, smart home systems, IoT devices, and educational electronics projects.
