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 This board only has three pins: VCC, GND and OUT. You can power this board from 2.5V to 5.5V. OUT is a powerful opencollector output. The following table adds some more technical Information about this board: Operating Voltage: 2.5 - 5.5 Volts Current consumption: 1.7mA @ 3V Out pin current sinking: 750mA @ 30V Detection pulse width: 40mS Detection Range: Approx 9 ft. Weight: 2.1 Grams Dimensions: 37mm L by 12mm W by 6mm H
