Hand Clap Sensor VM-Clap1


Elmwood Electronics has stopped accepting orders. This product might be available at PiShop.ca. Please check this blog post about our recent team merger.

The VM­Clap1 is a low cost, low power, microprocessor based hand clap sensor which will ignore background noises such as human speech or music and will only react to hand clapping or finger snapping. Once a detection is made, it will momentarily light up its blue LED and change its output from the normally open collector output to GND. This enables you to easily connect this sensor to your board.

Hooking It Up
