Digital Digital Digital relative relative relative relative humidity humidity humidity humidity & temperature emperature emperature emperature sensor AM2302/DHT22
1. Feature Feature Feature Feature & Application Application Application Application:
*High precision
*Capacitive type
*Full range temperature compensated
*Relative humidity and temperature measurement
*Calibrated digital signal
*Outstanding long-term stability
*Extra components not needed
*Long transmission distance, up to 100 meters

2. Description: Description: Description: Description:
AM2302 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 AM2302 to be suited in all kinds of
harsh application occasions. Single-row packaged with four pins, making the connection very convenient.
