  • AM2320 digital temperature and humidity sensor is a temperature and humidity sensor with a digital signal output. The use of special temperature and humidity collection technology, to ensure that the product has a high reliability and excellent long-term stability. The sensor consists of a capacitive humidity sensor and a high precision integrated temperature measuring element, and is connected with a high performance microprocessor. The product has excellent quality, fast response, strong anti-interference ability, high cost performance advantages.

  • AM2320 communication mode using single bus, standard I2C two ways of communication. Standard single bus interface, so that the system integration becomes simple and quick. Ultra small size, very low power consumption, signal transmission distance of 20 meters or more, so that it becomes the best choice for all kinds of applications and even the most demanding applications. I2C communication mode adopts standard communication time sequence, the user can hang directly on I2C communication bus, without additional wiring, use simple. Two kinds of communication methods are used in the direct output of the temperature compensation of humidity, temperature and the CRC and other digital information, the user without the digital output for two times, there is no need for temperature compensation, can get accurate temperature and humidity information. Two kinds of communication modes are free to switch, the user can choose freely, the use is convenient, it should be widely used in the field. Products for the 4 lead, connecting convenience, a special form of packaging can be based on user needs and provide.
