Capacitive Sensor


Posted on Jun 30, 2012

The purpose of this circuit is to animate shop-windows by means of a capacitive sensor placed behind a post-card-like banner. The card is placed against the glass inside the shop-window, and the visitor can activate the relay placing his hand on the card, from the outside. Especially suited for toy-shops, the circuit can activate model trains, small electric racing cars, lights etc. Further applications are left at user`s imagination. Adopt it to increase the impact of your shop-window on next Christmas season!
