Wirelessly control AC outlets with an Arduino-powered proximity switch

 After finding some inexpensive wireless AC outlet controls in a bargain store, Jacob Clarke decided to put them to good use with an Arduino. His device uses an ultrasonic distance sensor which monitors for the presence of a person sitting at a desk, and if they're there for a minimum period of time the AC outlet is activated by the remote control connected to the Arduino - for example:

This is a clever, inexpensive and safe method of controlling AC outlets with an Arduino. For more discussion visit reddit, and sketch can be found here. And  for more, we're on twitter and Google+, so follow us for news and product updates as well. 

If you're new to Arduino and want to join the fun, the first step is a solid board for your projects - our Freetronics Eleven - the Arduino-Uno compatible with low-profile USB socket, onboard prototyping space and easy to view LEDs:
