AM2322 Humidity Temperature Sensor

AM2322 digital temperature and humidity sensor is a temperature and humidity sensor with self-calibrated digital signal output.

The product has excellent quality, super-fast response, strong anti-interference ability, high cost-performance ratio.

It has two communication modes: single bus and standard I2C. The Standard single bus interface makes system integration easy and fast.The ultra small volume, the extremely low power consumption, the signal transmission distance can reach more than 20 meters, making it become the best choice of all kinds of applications and even the most demanding application situation. I2C communication mode adopts the standard communication sequence. Users can directly hang on the I2C communication bus, no additional wiring, easy to use. Both modes of communication use digital information such as humidity, temperature and check CRC, which are directly output after temperature compensation.

Users do not need to carry out secondary calculation of digital output, nor need temperature compensation for humidity.
