DHT11 temperature and humidity sensor

DHT11 is the simplest temperature and humidity sensor that can find. It connects to Dasduino in a very simple way using just one code (video below) and gives you back two variables as temperature and humidity. It does not require extra calibration to work, just plug it in and use it. Look up the library for it in the TUTORIAL section.

* Voltage: 3-5V

* Current: max. 2.5mA

* Humidity measurement range 20-80% with 5% accuracy

* Temperature measurement range: 0-50 degrees Celsius with +- 2% accuracy

* Dimensions: 15.5 x 12 x 5.5 mm / 0.6" x 0.5" x 0.2"
