AM2302 Temperature and Humidity Sensor output calibrated digital signal. It also apply exclusive digital-signal-collecting-technique and humidity sensing technology and assuring its reliability and stability. Moreover, Its sensing elements is also connected with 8-bit single-chip computer.
Also, Every sensor of this model is temperature compensated and calibrated in accurate calibration chamber and the calibration-coefficient is saved in type of program in OTP memory. when the sensor is detecting, it will also cite coefficient from memory.
Even so, Small size & low consumption & long transmission distance(100m) enable AM2302 to be suited in all kinds of harsh application occasions. Single-row packaged with four pins also makes the connection very convenient.
