[A-3-3]DHT11 Temperature And Humidity Sensor Module with LED and Cable

The DHT11 is a basic, ultra 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 in your code please use sensor reading interval at every 2 seconds or more.
