DHT22 Digital Temperature and Humidity Sensor

DHT22 is a Digital Temperature and Humidity Sensor Module. It’s a low cost temperature and humidity sensor with a capacitive humidity sensor and a thermistor to measure the surrounding air, and provide a digital signal on the data pin. It is very easy to interface, but requires careful timing to capture data.
Connect the first pin on the left to 3-5V power source and the second pin to your data input pin. The rightmost pin is a ground pin.
