Humidity Temperature Sensor DHT22

DHT22 output calibrated digital signal. It utilises exclusive digital-signal-collecting-technique and humidity sensing technology, assuring its reliability and stability.Its sensing elements are connected to an 8-bit single-chip microcontroller. 

Every sensor of this model is temperature compensated and calibrated in accurate calibration chamber and the calibration-coefficient is saved in type of programme in OTP memory when the sensor is detecting, it will cite coefficient from memory. 

Small size & low consumption & long transmission distance(20m) enable DHT22 to be suited for all kinds of harsh application occasions.

Single-row packaged with four pins, making the connection very convenient.
