1、Infrared PIR Motion Sensor: It can detect human movement by detecting infrared ray emitted by human body. 2、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. 3、360 Degrees Cone Angle Detecting Range: High and stable sensitivity, effectively save energy and improve efficiency. 4、Adjustable 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 tim 5、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 Description: This switch with PIR Infrared Motion sensor detector, can be used in corridors, bathrooms, basements, warehouses, garages and other places to achieve automatic control functions. High and stable sensitivity, effectively save energy and money for you. 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. Adjustable 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.
