The sound-responsive light control switch module is a simple system to be used in many sound-controlled devices, e.g. a clap light switch. If the conditions are right, i.e. it is twilight or dark night and there will be a loud sound, the system will turn on the lighting or other connected device for 45 seconds. After this time, the system disconnects the power supply at the output and goes into standby mode. The system reacts to a single clap of hands, it can also react to a dog barking or the sound of a spoon falling. This sensor sleeps during the day when it is light, thanks to the photoresistor, and therefore it will turn on the light only when it is dark.
