DescriptionDHT22 Digital Temperature and Humidity Sensor Module AM2302The DHT22 Digital Temperature and Humidity Sensor Module AM2302 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed).Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old.Simply connect the first pin on the left to 3-5V power, the second pin to your data input pin and the rightmost pin to ground. Although it uses a single-wire to send data it is not Dallas One Wire compatible! If you want multiple sensors, each one must have its own data pin!Note: Color of connecting wire may vary. You may get any color while shipping.Features :High precisionCapacitive typeFull range temperature compensatedRelative humidity and temperature measurementCalibrated digital signalOutstanding long-term stabilityExtra components not neededLong transmission distanceLow power consumption4 pins packaged and fully interchangeablePackage Includes :1 x DHT22 Digital Temperature and Humidity Sensor Module AM23021 x Connecting Cable
