ADIY DHT11 Sensor Module

This is a very popular, ultra-low cost digital temperature and humidity sensor. It uses a
capacitive humidity sensor, and a thermistor to measure the surrounding air temperature. The
result is available via a digital signal on the data pin (no analog input pins needed). It is 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. But, for most applications this is not an
issue at all.
