1. Voltage:Constant voltage DC3.7V-24V 2. Current:max 3A 3. Sensting distance not over 6M for reference(Can penetrate over 25CM Signal can penetrate walls,The penetration distance vary depending on the material medium) 4. when people near 0-6mThe light turns on when it detects a person or pet. It turns off after they leave the detection zone. If someone remains active within the detection area, the timer keep resetting/extending. If a person or pet stays motionless, the motion sensor be unable to detect them (causing the light to turn off after the last detected movement). 5. Work all day,no matter day or night The PIR sensor can sense the medium materials: wood plate, rock plate, stone, paper, acrylic, plastic, and other non-metallic conductor materials. Induction distance: The different thickness sensitive is different, the thinner the better Please don't close to metal materials to avoid interference. Please tightly adhere the product to the material that needs to be penetrated.
