When disassembling, you need to be careful, otherwise the built-in circuit is easy to disconnectThis product solves the pain points that human sensors cannot detect the presence of a static human body. Using advanced infrared radar technology, it can accurately detect whether there are people in the area, whether it is active or static.Accurately perceive the indoor light intensity, Qinger automatically adjusts the brightness of the light according to the brightness of the indoor light, controls the light switch, and through radar detection, it is truly realized that the lights are on and the lights are off when people are walking.Built-in multiple people and brightness sensors, through the MFAI intelligent algorithm can be refinedQuasi-identify the presence of people in the room. Conical detection range, suitable for room area of 6-25 square , sensing angle of . The diameter of the human body sensing range is 5 (installation height 2.8 , ground projection)You can indoor movement in real time through your mobile phone, and you can the opening and closing conditions of indoor lights in real time.With other smart devices, it can realize automation and scene control. makes smart hardware respond faster and control smoother. Can still be used even if is disconnectedTransmitting power: 2.4GHzCommunication distance: 100m (open environment)Detection angle: less than 90degreeLight detection: supportPower input: AC200VWorking temperature: -10Celsius~ 55Celsiustype: BColour:WhiteMaterial: ABStype:WIFIPackage Contents:1 x Sensor1 CordOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing.
