AM2302 Humidity Capacitance Digital Temperature and Humidity Module is a temperature and humidity composite sensor with calibrated digital signal output. It uses a dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure that the product has a very high reliability and excellent long-term stability. The sensor includes a capacitive wetting element and a high-precision temperature measuring element and is connected to a high-performance 8-bit microcontroller. So the product has excellent quality, ultra-fast response, anti-interference ability, cost-effective and so on. Each sensor is calibrated in an extremely accurate humidity calibration room. The calibration coefficients are stored in the form of a program in the microcontroller, and these calibration coefficients are called internally during the processing of the detection signal. Standard single bus interface, the system integration has become simple and quick. Ultra-small size, very low power consumption, signal transmission distance of up to 20 meters or more, making it the most demanding applications for all types of applications. The product is 3-lead (single bus interface) for easy connection. Special package can be provided according to user needs.
