Introduction to the product
AM2305 Digital Temperature & Humidity Sensor is a temperature and humidity combined sensor been calibrated digital signal output. The sensor includes a capacitive sensor wet components and a DS18B20 temperature measurement device and connected with a high-performance 8-bit microcontroller. Each AM2305 sensors are an 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, system integration becomes simpler and quicker. Ultra-small size, low power consumption, signal transmission distance up to 20 meters or more, making it the best choice of even the most demanding applications in a variety of applications then, the product leads to three core shielded cables.
