Description:
- Am2305 output calibrated digital signal. It applys 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 coefficient from memory.
- Small size & low consumption & long transmission distance(100m) enable AM2305 to be suited in all kinds of harsh application occasions. Single-row packaged with four pins, making the connection very convenient.
