Large amount of data acquisition with greater accuracy and stability, DHT22 holds better position than DHT11. The sensor is precisely calibrated. The highly stable, anti-interference ability of the 8 bit microcontroller makes the DHT22 to process the large amount of data from the sensing unit.

The calibration coefficient isstored in the form of a program OTP memory which is accounted by the detection signal. DHT22 is a 4-pin single row pin package with easy connection pinouts.

DHT22 consumes low power and can be installed easily with any kind of microcontroller board. Simply connect the first pin on the left to 3-5V power, the second pin to data input pin and the right most pin to ground.
