Gadget Freak Case #116: Security System Calls Your Cell

By Design News Staff -- Design News, February 24, 2008

Gadget Freak Bill Bowden has created a security system that calls you when an alarm is triggered. You can set it up to indicate intrusion into a door, window, office or pool. It can also connect to a panic button. The circuit includes a small PIC microcontroller, an assembly program and a handful of other parts that can be designed to detect the interruption of a switch closure or the connection of a panic button. When the circuit is tripped, the gadget dials your number and indicates what device has been triggered.

The construction cost for the security circuit is less than $30. As well as circuit parts, you will also need a PIC programmer to load the program into the microcontroller.
