DHT22 Temperature Humidity Sensor is a Medium Precision Sensor with 1-Wire Data Bus. The Aosong AM2302, better known as DHT22,  is a calibrated, integrated humidity and temperature sensor with a 1-wire communication interface which only requires 1 IO pin on your microcontroller.

The sensor provides 16 bit resolution and consumes only about 0.3mA when active (0.06mA in standby). It can operate on a supply voltage of 3.5 to 5.5V.

DHT22 Temperature Humidity Sensor is not only easy to connect, the available libraries (e.g. for Arduino) are also very easy to use.

This sensor module is a more precise device than the cheaper DHT11. See a comparison of the main features:

  • Humidity: 0-100% with 2-5% accuracy (DHT11: 20-80% with 5% accuracy)
  • Temperature: -40 to 80C with +/- 0.5C accuracy (DHT11: 0-50C with 2%)
  • Sampling rate: 0.5 Hz (DHT11: 1 Hz)

The module's body size is 15.1mm x 25mm x 7.7mm and it comes with 4 pins with 0.1" (2.54mm) spacing.
