This product adopts infrared human body induction and light control technology. Control the load by detecting the movement of the human body (more practical, stable, energy efficient and user-friendly than traditional Contact, voice-controlled switches). The light in the induction area is on, and when the person leaves, it will be off automatically according to the set time.
