First, the product overview
AM2302 Humidity Capacitance Digital Temperature and Humidity Module is a temperature and humidity sensor with calibrated digital signal output. It uses a dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure that products with high reliability and excellent long-term stability. The sensor includes a capacitive sensing element and a high-precision temperature measurement element, and with a high-performance 8-bit microcontroller connected. Therefore, the product has excellent quality, ultra-fast response, anti-interference ability, cost-effective advantages. Each sensor is calibrated in an extremely accurate humidity calibration chamber. Calibration coefficients are stored in the form of a program in the microcontroller, the sensor within the detection signal processing to call these calibration coefficients. Standard single bus interface, making system integration easier and faster. Ultra-small size, low power consumption, signal transmission distance of up to 20 meters or more, making it all kinds of applications and even the most demanding applications the best choice. Products for the 3-pin (single bus interface) to facilitate connection. Special packaging can be provided according to user needs.
