HM2322 digital temperature and humidity sensor is a temperature and humidity sensor with self-calibrated digital signal output.Adopt special temperature and humidity collection technology to ensure high reliability and excellent long-term stability.The sensor consists of a capacitive humidity sensor and a high-precision integrated thermometer and is connected to a high-performance microprocessor.The product has excellent quality, super-fast response, strong anti-interference ability, high cost-performance ratio and so on. HM2322 communication mode adopts single bus, standard I 2 C two kinds of communication mode.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. I 2C communication mode adopts the standard communication sequence.Users can directly hang on the I 2 C 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.Accurate temperature and humidity information can be obtained.The two communication modes can be freely switched, users can choose freely, easy to use, and should be widely used.Product for 4 lead, easy to connect, special packaging form can be provided according to user needs.
