Dear guys I'm a new user of Arduino.

My friends and me are planning a simple model of home automation and we bought some sensors including the temperature and humidity, precisely the DHT11 http://www.seeedstudio.com/depot/twig-temphumi-sensor-p-745.html
But I noticed that contrary to the others, it has got 4 pins, not 3 pin. And It's marked as Vcc, GND, SIG and NC.
You may kindly refer to how I connect it to Arduino and have a code to try and collect data. Excuse me but we are very inexperienced and I would like your help. If you want more information just ask. Thank you in advance.  :)


P.S.: excuse me for the bad english  :smiley-mr-green:

NC usually means Not Connected, does that help?

Cheers,
