Product Description
digital signal via single-bus Digital-output relative humidity & temperature sensor with Original authentic
Digital-Output Relative Humidity & Temperature Sensor

AM2301 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 AM2301 to be suited in all kinds of harsh application occasions.
Single-row packaged with four pins, making the connection very convenient.
