First, product overview;

CM2320 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.

CM2320 communication mode adopts single bus, standard I 2 C two kinds of communication mode.Standard single bus interface makes system integration easy and fast.Ultra-small volume, extremely low power consumption, and the distance of signal transmission can reach more than 20 meters, making it the best choice for all kinds of applications and even the most demanding applications.The I2C communication mode adopts standard communication sequence, the user can hang directly on the I2C communication bus, no extra wiring is needed, and the use is simple.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.

Second, the scope of application;

HVAC, Dehumidifier, testing and testing equipment, Consumer goods, Automobile, automatic Control, data Recorder, Weather Station, Home Appliances, humidity Adjustment, Medical, and other related humidity Measurement controls.

Third, product highlight;
