1. Product Overview AM2302 Humidity Capacitor Digital Temperature and Humidity Module is a temperature and humidity composite sensor with calibrated digital signal output. It uses digital module acquisition technology and temperature and humidity sensing technology to ensure that the product has high reliability and long-term stability. The sensor includes a capacitive humidity sensing element and a high-precision temperature measuring element, and is connected with a high-performance 8-bit single-chip microcomputer. Therefore, the product has the advantages of quality, ultra-fast response, strong anti-interference ability, and high cost performance. Each sensor is calibrated in our humidity calibration room. The calibration coefficients are stored in the single-chip microcomputer in the form of a program, and these calibration coefficients must be called during the processing of the detection signal inside the sensor. Standard single bus interface makes system integration easy and quick. Ultra-small size, low power consumption, and signal transmission distance of up to 20 meters or more, making it a good choice for various applications and even for demanding applications. The product is easy to connect with 3 leads (single bus interface). Special packaging forms can be provided according to user needs. 2. Scope of application HVAC, dehumidifier, testing and inspection equipment, consumer products, automobiles, automatic control, data loggers, home appliances, humidity regulators, medical care, weather stations, and other related humidity detection and control. 3. Product highlights: Energy consumption, long transmission distance, full automatic calibration, use of capacitive humidity sensors, complete interchangeability, standard digital single bus output, long-term stability, and use of high-precision temperature measurement components. 4.
