Description:This switch is based on infraredtechnology, it will automatic turn on when the sensor detects the change of theinfrared spectrum of the human body in the sensing range. High and stablesensitivity, automatic turns on/off depended on people movation. Friendly andconvenient, safe and energy-saving.Features:Infrared PIR Motion Sensor: It can detecthuman movement by detecting infrared ray emitted by human body.Intelligent Brightness Sensor: It adoptsphotosensitive control, it will not turn on the light during the daytime orstrong light environment, or you can choose to turn on the light during the anylight environment.360 Degrees Cone Angle Detecting Range:High and stable sensitivity, effectively save energy and improve efficiency.Time Delay: intelligent sensing, it willautomatically close after a delay after the person leaves. After it is turnedon within the delay period, if there is no human activity, there is a time fordelaying the work for a certain period of time and adjusting the delay timewithin the appropriate range.Wide Applications: Widely used on themotion-activated lighting, corridors, bathrooms, basements, warehouses, garagesand other places, automatic exhaust ventilation fan and other electricalappliances and other functions.Temperature Compensation: Built-intemperature compensation chip, reducing the impact sensing distance by thetemperature.Specifications:Operating voltage: 85-265V, ACInstallation method: embedded installationMaximum load: resistive load 800WWiring method: BipolarOutput Mode: Inductive OutputLight control range: 5 Lux ~ 500Lux ± 20%(adjustable sensitivity)Delay range: 16~350s, ± 30% (adjustable delay)Induction mode: passiveSensing angle: 360 degree cone angleSensing distance: 5-8mInstallation method: wall mounting, suctionpoint installation, ceiling installationSize: 5.2*5.2*6.5cm/2.05*2.05*2.56inchColor: WhitePackage List:1 x Infrared Motion Sensor Switch1 x Manual.
