DHT22 Temperature and Humidity Sensor Module
DHT22 Temperature and Humidity Sensor Module output calibrated digital signal. It utilizes exclusive digital-signal-collecting-technique and humidity sensing technology, assuring its reliability and stability. Its sensing elements are connected with an 8-bit single-chip computer. Every sensor of this model is temperature compensated and calibrated in an accurate calibration chamber and the calibration-coefficient is saved in the type of program in OTP memory, when the sensor is detecting, it will cite coefficient from memory.
