AM2322 Temperature and Humidity Sensor Product Overview
AM2322 The digital temperature and humidity sensor is a kind of temperature and humidity composite sensor with the output of calibrated digital signal. The special temperature and humidity collection technology is adopted to ensure the high reliability and long-term stability of the product.The sensor includes a capacitive sensing element and a high-precision integrated temperature measurement element, which is connected to a high-performance microprocessor.The product has high quality, super fast response, strong anti-interference ability and high cost performance.
AM2322 communication mode adopts single bus, standard I squared C communication mode.Standard single bus interface makes system integration easy and fast.The super small volume, extremely low power consumption, the signal transmission distance can reach up to 20 meters, making it the best choice for all kinds of applications and even the most demanding applications.The I squared C communication mode adopts standard communication timing, and the user can be directly attached to the I squared C communication bus, with no additional wiring and simple use. Two kinds of communication mode is used directly output after temperature compensation, humidity, temperature and the CRC check and other digital information, users need to secondary calculation of digital output, also need not to compensate the temperature humidity, accurate temperature and humidity information can be got.The two modes of communication are free to switch, users are free to choose, easy to use, and should be widely used.The product is 4 lead wire and convenient connection. Special packaging can be provided according to user's demand.
