AM2302 AM2302B Digital Temperature and Humidity Sensor - Single Bus

AM2302 AM2302B Single Bus Digital Temperature and Humidity Sensor

AM2302B is a temperature and humidity composite sensor with calibrated digital signal output. Special digital module aggregation technology and temperature and humidity sensing technology are used to ensure that the product has extremely high reliability and long-term stability. The sensor includes a capacitive humidity sensing element and a high precision temperature measuring element. It is connected with a high-performance 8-bit single-chip microcomputer.

The product has the advantages of excellent quality, ultra-fast response, strong anti-interference ability and high cost performance. Each sensor is calibrated in a highly accurate humidity calibration chamber. The calibration coefficients are stored in the microcontroller in the form of a program, and these calibration coefficients are named in the internal processing of the sensing signal of the sensor. The standard single bus interface makes system integration easy and fast. Its ultra-small size, extremely low power consumption and signal transmission distance of up to 20 meters or more make it the choice for a variety of applications and demanding applications. The product is easy to connect with 3 cables.
