An Arduino and Twilio-powered alarm system

After his wife was concerned about leaving their valuables in a moving truck for the night, Tim Flint turned to the Arduino platform to find a solution to calm her nerves and also create a simple yet connected alarm system. He used an infra-red distance sensor (which could be replaced with a PIR or other motion detector) connected to an Arduino with a WiFi shield.

Once movement has been detected, the Arduino contacts the Twilio service that generates voice calls and SMS text messages to alert of an impending theft. A quick demonstration is in the following video:

Although it seems like overkill, it's an interesting application for Twilio, and to learn more and find links to more tutorials check out Tim's website. And for more, we're on twitter and Google+, so follow us for news and product updates as well. 

If you need to add your own external circuitry to prototype with an Arduino or compatible board, pm one or more of our range of ProtoShields. From the tiny LeoStick to the Mega range, we offer a complete range for you to work with.
