AM2302 output calibrated digital signal. It applies an exclusive digital-signal-collecting-technique and humidity sensing technology, assuring its reliable and stable. Its sensing elements are connected to a 8-bit single-chip controller.
Every sensor of this model is temperature compensated and calibrated in accurate calibration chamber and the calibration-coefficient is saved in OTP memory, when the sensor is detecting, it will get coefficient from memory.
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, making the connection very convenient
