Description

Switch module controlled by sound 3-30V 1A – clapper

Light control switch module, responsive to sound is a simple circuit for use in many sound-controlled devices, for example: light switch on clap.

• If the conditions are right, that is, it is twilight, or dark night and there will be a loud sound then the circuit will turn on the lights, or any other connected device for 45 seconds. After this time, the circuit disconnects power at the output and goes into standby mode.
• The system responds to a single clap of the hands, and can also respond to the barking of a dog or the sound of a falling spoon.
• This sensor is dormant during the day when it is light, thanks to a photoresistor, and will therefore only switch on the light when it is already dark.
