Sound Sensitive 12V Bulb Control | Sound control light

The sound sensor has a thin piece of material called a diaphragm that vibrates when hit by sound waves (similar to how your eardrum vibrates when hearing a sound) signal wave generator. The vibration of the diaphragm is converted by the sensor into an electrical system.

A sound sensor is defined as a module that detects sound waves through their intensity and converts them to electrical signals. sound sensor consists of an in-built capacitive microphone, a peak detector, and an amplifier (LM386, LM393, etc.) that's highly sensitive to sound.

Once installed, the switch is connected to an app on a smartphone or tablet system. The switch, and therefore the light connected to it, can then be controlled remotely through the app or smart speaker sound generator.

LED controller is a special chip processing control LED lights display function of the switching system. The controller will control the driver circuit according to the program input in the advanced circuit diagram.

Unlike incandescent and fluorescent bulbs, LED bulbs do not have filament or firing arcs, which means that they have no moving parts that can cause a buzzing sound generator. However, they can still produce a buzzing sound due to improper dimming or electromagnetic interference from other device systems.
