Features: Using sensing technology to accurately capture human activity and automatically turn on or off light. Solved the inconvenience of manual operation for traditional switches. Not need for complex wiring and tool installation, simply insert and use, reducing installation time. By using intelligent sensing to control lighting, unnecessary power consumption can be avoided for long terms, effectively reducing energy waste. Light turns on when people come, and turns off 30s after people leave. Builted in overloads protections mechanism ensures long-terms stability and safety, preventing circuit failures.
