DHT22/AM2302 Digital Temperature & Humidity Sensor

DHT22 Temperature and Humidity Sensor is a premium quality Humidity & Temperature Sensor from Techtonics. All DHT22 Digital Temperature & Humidity Measurement Sensor are manufactured by using quality assured material and advanced techniques, which make them up to the standard in this highly challenging field.

DHT22 Digital Temperature & Humidity Sensor is a 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 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!
