DHT22 Digital Temperature and Humidity Sensor Module AM2302

DHT22 Digital Temperature and Humidity Sensor Module AM2302DESCRIPTION The DHT22 Digital Temperature and Humidity Sensor Module AM2302 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
