Description:
AM2303 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
coefficient from memory.
Small size & low consumption & long transmission distance(20m) enable AM2303 to be suited in all kinds of
harsh application occasions.
Single-row packaged with four pins, making the connection very convenient.
