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. Can identify day and night (that is, you can manually adjust the knob to choose day and night work), product performance is stable, safe and convenient, energy saving. Intelligent lighting, security products of choice. Applicable place: Door, corridor, elevator, balcony, bathroom, mirror, wardrobe, cabinet, warehouse, basement, garage and other indoor and outdoor . This product can be used for resistance and inductive load of incandescent lamp, fluorescent lamp, LED lamp and automatic switch control of electrical equipment. Notes:1. The installation of the switch shall be carried out by a qualified electrician.2. Before installation, turn off the main power supply (live operation is strictly prohibited), install the switch as required, connect the wire according to the drawing and fix the switch, and then connect the main power supply.3. Please connect the wires strictly according to the wiring diagram.4. Do not overload or use beyond the scope. Technical parameters: 1. Operating voltage: AC 110 ~ 220V. Power consumption: 0.1w; Ambient temperature: -20 ~ +40 2. Delay time: 5 seconds to 10 minutes can be adjusted by knob 3. Maximum load power: 1000W (resistance load such as incandescent lamp), 300W (inductive load such as fluorescent lamp, LED lamp, etc.) 4. Induction distance: 12 +/- 2 meters; Induction Angle: 180 5. Ambient illumination: 3 (at night) to 2000LUX can be adjusted by knob. senses both day and night whenit is in the position of the sun; To the moon's position only at night. 6. Installation height: 1.8 to 4.5 meters; Protection grade: IP44(suitable for outdoor and indoor use) 7. The maximum induction distance of 12 meters refers to the maximum detection distance of the infrared induction elements. In actual use, the actual detection distance may not reach 12 meters due to the environmental temperature, installation , the position of the detected object, cold and hot air flow and other factors. colour: white Material: ABS Size: 110x85x78mm Package Contents: 1 x infrared motion sensor Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
