AM2303 Digital Temperature and Humidity Sensor Anti-humidity


Always Free Shipping


AM2303 is a digital temperature and humidity sensor output signal containing a calibrated digital temperature and humidity combined sensor. It uses a dedicated digital modules and acquisition of temperature and humidity sensor technology to ensure that products with high reliability and excellent long term stability.

Sensor consists of a capacitive sense element and a wet DS18B20 temperature device, 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 AM2303 sensors are extremely accurate calibration of humidity calibration chamber. Calibration coefficients stored in the OTP program memory, internal sensor, signal processing in the detection process to call these calibration coefficients. Single-wire serial interface, allowing the system to become simpler and quicker integration. Ultra-small size, low power consumption, signal transmission distance up to 20 meters, making it a wide range of applications and even the most demanding applications the best choice is the product lead for the three-core shielded cable.
