DHT22 Digital Temperature-Humidity Sensor

CIRCUiTSFUN

ADA00003

SPECiFiCATiONS


DHT22 output calibrated digital signal. It utilizes 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 the coefficient from memory.
