DHT22 Digital Temperature & Humidity Sensor

The DHT22, also known as AM2302, is an upgraded digital temperature and humidity sensor offering improved accuracy and a wider measurement range compared to the DHT11. It is compatible with Arduino, Raspberry Pi, and other microcontrollers, making it ideal for DIY electronics, environmental monitoring, and home automation projects.

Specifications:

• Temperature range: -40°C to 80°C
• Temperature accuracy: ±0.5°C
• Temperature resolution: 0.1°C
• Humidity range: 0–100% RH
• Humidity accuracy: ±2% RH
• Response time: ~2 seconds
• Interface: Single-wire digital
  

For beginners or simple indoor projects, the DHT11 is a great alternative. Both sensors are compared in our Best Arduino Digital Temperature Sensors guide.
