Special temperature and humidity acquisition technology is adopted to ensure the product has high reliability and excellent long-term stability. The sensor consists of a capacitive humidity sensor and a high accuracy integrated temperature sensor connected to a high performance microprocessor. The product has the advantages of excellent quality, ultra-quick response, strong anti-interference ability and high cost performance.AM2120 adopts single bus communication mode and standard single bus interface, which makes system integration easy and quick. Ultra-small size, extremely low power consumption, signal transmission distance can reach more than 20 meters, making it the best choice for all kinds of applications and even the most demanding applications. By directly outputting digital information such as humidity, temperature and calibration after temperature compensation, users can get accurate temperature and humidity information without secondary calculation of digital output and temperature compensation of humidity. The product is 4 leads, easy to connect, special packaging forms can be provided according to user needs.Package Includes:1 X AM2120 Digital Temperature and Humidity Sensor
