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.   Specifications: Product model number: TDL-9958R Functional Description : Relay Control Load Operating voltage: 12V Working temperature: -10 °C ~ +40 °C Static power consumption: 0.05W  Load power: 100W Load capacity: all kinds of lamps, all kinds of electrical appliances Output Mode: Inductive Output Light control range: 5Lux ~ 500Lux ± 20% (adjustable sensitivity) Delay range: 30~350s, ± 30% (adjustable delay) Induction mode: passive Sensing angle: 360 degree cone angle Sensing distance: 5-7 m Installation method: suction point installation/ Ceiling installation Size: 89*89*40mm/ 3.5* 3.5* 1.6inch   Package List: 1 * Infrared Motion Sensor Switch 1 * Accessories Note:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
