AM2302 temperature and humidity sensor
AM2302B Humidity Capacitor Digital Temperature and Humidity Module is a temperature and humidity composite sensor with calibrated digital signal output. It uses dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure that the product has extremely high reliability and excellent 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 excellent quality, ultra-fast response, strong anti-interference ability, and high cost performance. Each sensor is calibrated in an extremely accurate humidity calibration room. The calibration coefficients are stored in the single-chip microcomputer in the form of a program, and these calibration coefficients are called in the sensor's internal detection signal processing. Standard single bus interface makes system integration easy and quick. Ultra-small size, extremely low power consumption, and signal transmission distance of up to 20 meters or more, making it the choice for various applications and demanding applications. The product is 3-lead (single bus interface) for easy connection.
