Description: This switch is based on infrared technology, it will automatic turn on when the sensor detects the change of the infrared spectrum of the human body in the sensing range. High and stable sensitivity, automatic turns on/off depended on people movation. Friendly and convenient, safe and energy-saving. Features: Infrared PIR Motion Sensor: It can detect human movement by detecting infrared ray emitted by human body. Intelligent Brightness Sensor: It adopts photosensitive control, it will not turn on the light during the daytime or strong light environment, or you can choose to turn on the light during the any light environment. 360 Degrees Cone Angle Detecting Range: High and stable sensitivity, effectively save energy and improve efficiency. Time Delay: intelligent sensing, it will automatically close after a delay after the person leaves. After it is turned on within the delay period, if there is no human activity, there is a time for delaying the work for a certain period of time and adjusting the delay time within the appropriate range. Wide Applications: Widely used on the motion-activated lighting, corridors, bathrooms, basements, warehouses, garages and other places, automatic exhaust ventilation fan and other electrical appliances and other functions. Temperature Compensation: Built-in temperature compensation chip, reducing the impact sensing distance by the temperature. Specifications: Operating voltage: 85-265V, AC Installation method: embedded installation Maximum load: resistive load 800W Wiring method: Bipolar Output Mode: Inductive Output Light control range: 5 Lux ~ 500Lux ± 20% (adjustable sensitivity) Delay range: 16~350s, ± 30% (adjustable delay) Induction mode: passive Sensing angle: 360 degree cone angle Sensing distance: 5-8m Installation method: wall mounting, suction point installation, ceiling installation Size: 5.2*5.2*6.5cm/2.05*2.05*2.56inch Color: White Package List: 1 x Infrared Motion Sensor Switch 1 x Manual .
