The infrared motion sensor is made of high-quality plastic, which is not easy to age, strong and durable, and can be used for a long time. d the time. The LX Knob is used to adjusts light perception. Turn it clockwise to for all-weather sensing, and turn it counterclockwise to for sensing in a dark environment.The infrared motion sensor human body sensor switch is designed for environmental protection and energy saving. The sensor switch adopts infrared human body motion sensor technology, when a person enters the sensing range, the is turned on immediately, and the is off according to the set time after the person leaves, which can realize intelligent control and energy saving.When people are active in the sensing area, the will continue to extend the time. The Knob is used to adjusts light perception. Turn it clockwise to for all-weather sensing, and turn it counterclockwise to for sensing in a dark environment.Detection distance, ambient light and delay time are adjustable according to your actual demand. Ceiling or wall-mounted installation, suitable for corridors, corridors, garages, terraces, toilets, etc., widely used to control LED lights, compact fluorescent lights, incandescent bulbs, alarms, exhaust fans, etc., very convenient to use and consumption saving.The LED infrared sensor head is automatic, convenient, safe and practical. The detection angle of this infrared detector is 160.Name: Infrared Sensor SwitchVoltage: 100-240VMaterial:plasticcolour:BlackPackage Contents:1 x Sensor SwitchOnly 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.
