DHT21 AM2302 Temperature and Humidity Sensor
AM2302 digital temperature and humidity sensor is a calibrated digital composite signal output of the temperature and humidity sensor. It dedicated digital module acquisition technology and the temperature and humidity sensor technology, ensure that the product has very high reliability and excellent long-term stability.
Includes a capacitive moisture sensor element and a temperature measuring device, and connected to a high-performance 8-bit microcontroller. So the product has excellent quality, super-fast response, strong anti-interference ability, extremely high performance-price ratio.
Every AM2302 sensor in extremely precise humidity calibration laboratory calibration.Calibration coefficient in the form of a program stored in the OTP memory, inside the sensor in the process of detecting signal processing to invoke the calibration coefficient. Single wire serial interface, system integration becomes simple and fast. Super small volume, low power consumption, signal transmission distance of 20 meters, making it all kinds of optimal choice of even the most demanding applications, products lead to three core shielded wire.
