Cypress Semiconductor

Chris and Vincent Paiano

Application Note

February 2009

The PSoC device is configured to react to the presence of studs through drywall to allow the user to easily locate a sturdy point to anchor or hang up an object. The sensor presents the studs via five LEDs. By holding the Stud Finder against a wall and moving it along horizontally, the different LEDs will light up as a stud is sensed.
