The AM2302 is a wired version of the DHT22 sensor, in a large plastic body.


It 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.


As usual Ladyada has released an excellent tutorial with all what you need to get this little low cost sensor up and working !
