It uses a dedicated digital modules capture technology and temperature and humidity sensor technology to ensure that products with high reliability and excellent long-term stability. Sensor includes a capacitive humidity sensing element and an NTC temperature measurement devices and with a high-performance 8-bit microcontroller connected. Therefore the product has excellent quality fast response anti-interference ability high cost and other advantages. Each AM2302 sensors are extremely accurate calibration of humidity calibration chamber. Calibration coefficients stored in the OTP program memory internal sensor the detection signal processing process to call these calibration coefficients. Single wire serial interface that allows quick and easy system integration. Ultra-small size low power consumption signal transmission distance up to 20 meters making it the most demanding types of applications and even applications is the best choice. Products for the 4-pin single row pin package. Packing List 1 x AM2302 temperature and humidity module http://m5.img.dxcdn.com/CDDriver/CD/sku.221256.rar
