AM2302 (wired DHT22) temperature-humidity sensor Biometric his is the solution you'veThe AM2302 is a wired version of the DHT22, 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
