DHT22 Temperature and Humidity Module 1.8 inches Flyback diode to protect yourThe DHT22 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). It's 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
