The DHT22 is a preciese, 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.
SNS-DHT22 is breadboard friendly module implementation of the popular low-cost DHT22 temperature and humidity sensor. It comes with compatible set of short female-female wires with proper headers to make it even easier to connect to any exposed pins of your main development board.
