What is the working principle of voice control light?

The voice-activated switch consists of electronic components sensitive to sound and other electronic components. The power supply is mainly controlled by external sounds. When the external sound reaches the rated decibel, the circuit will be connected. It has the characteristics of simple operation, flexibility, strong anti-interference ability and sensitive control.

applied range

The utility model relates to a lighting lamp, which is a light-controlled lamp controlled by natural light. The utility model uses a trigger element sensitive to natural light, a switch control element and a photosensitive resistor to form a switch control circuit to control the switch of the illuminating lamp. The control circuit has only seven components, which has the characteristics of simple structure, easy debugging and low cost.

Suitable for any environment that can be controlled by natural light, especially in public places. It can reduce the trouble of turning on and off the lights manually and avoid the waste of electricity caused by forgetting to turn off the lights.
