Features: Strong anti-interference: 5.8GHz working frequency is adopted, which is less affected by natural factor from the outside world, and its performances is stable and reliable. Automatic metering: Automatically identify the strength of the ambients light, and the light will turn on when the lighting requirements are set and there are people. Otherwise it will not light up. Adopting a combination of dials switches for adjustment, it has high accuracy, small error, convenient setting, and the contacts of the dials switches are not easily oxidized, with a long service life. Adopting solderless, untwisted wires, and press type wiring terminals, the wiring is convenient and firm. Used in combination with switches and lighting fixture, can be connects to LED lights, energy-saving lights, and incandescents lights. Suitable for bathrooms, stair, rooms, corridors, etc. Specifications: Material: PC Style: A/B/C Size: Approx. 6.9x3.6x2.3cm/2.72x1.42x0.90inch Working voltage: AC220V/50H Controllable load: ≤500W (LED ≤100W) ≤3 lights Standby power consumption: ≤1W Frequency ranges 5.8GHz ± 75MHz, ISMband Sensing distance (maximums): diameter 12m (472.44inch) x high 6m (236.22 inches) Detection angle: 360degrees (ceiling mounted), 180degrees (wall mounted) Sensing ranges: 10%/50%/75%/100% (gear combination selection, up to 10m) Delay time: 6 seconds/45 seconds/5 minutes/15 minutes (gear combination selection) Starting lighting: 2Lux/10Lux/30Lux/all weather (gear combination selection) Sensing speed: 0.5-3meters/second Installation height: maximums 6m/236.22inch Working temperature: -20 ℃~45 ℃ Package Includes: 1x Motion Sensors Switches note: Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order.
