Specifications

Unique relative temperature and humidity sensor,excellent long term stability and ultra low power consumption.

Description :

DYP-DHT22 output calibrated digital signal. It applys exclusive digital-signal-collecting-technique and humidity sensing technology, assuring its reliability and stability.Its sensing elements is connected with 8-bit single-chip computer. 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(100m)enable DHT22 to be suited in all kinds of harsh application occasions.Single-row packaged with four pins, making the connection very convenient.
