Humidity Sensor AM2302
AM2302 Product Overview:
AM2302 digital temperature and humidity sensor is a temperature and humidity combined sensor been calibrated digital signal output. Application-specific digital module acquisition technology and the temperature and humidity sensing technology, to ensure that products with high reliability and excellent long-term stability. The sensor includes a capacitive humidity sensitive element and a NTC temperature measurement devices, and connected with a high-performance 8-bit microcontroller. The product has excellent quality, fast response, anti-interference ability, cost and other advantages. Each AM2302 sensors are extremely accurate humidity calibration chamber for calibration. Calibration coefficients stored in the form of a program in OTP memory, internal sensor detection signal processing to call these calibration coefficients. The single wire serial interface, the system integration becomes simpler and quicker. The ultra-small size, low power consumption, signal transmission distance up to 20 meters, it is the best choice for a variety of applications and even the most demanding applications. The product is a 4-pin single row pin package. Convenient connection Special packages can be provided according to user needs.
