AM2302 Temperature And Humidity Sensor Datasheet


In this topic, we learn the AM2302 Temperature And Humidity Sensor Datasheet, AM2302 output calibrated digital signal. It applies exclusive digital-sign-collecting techniques and humidity sensing generation, assuring its reliability and stability. Its sensing elements connect to the 8-bit single-chip computer. Each sensor of this model is temperature compensated and calibrated in the correct calibration chamber and the calibration coefficient is stored in a type of program in OTP memory when the sensor is detecting, it will cite the coefficient from memory.

Small size & low consumption & long transmission distance (100) allow AM2302 to be suited to all styles of extreme application events. single-row packaged with four pins, making the connection very convenient.
