Light switch with high-sensitivity motion detector motion sensor switch Ceiling sensor 220-240V <ul class="a-un0rdered-list a-vertical a-spacing-mini"> <li class="a-spacing-mini"><span class="a-list-item">[220V-240V Infrared Motion Detector] 360° operating range for optimal motion detection. Motion detection range up to 6 meters. </span></li> <li class="a-spacing-mini"><span class="a-list-item">[Dimmable Light Sensor] This motion sensor switch has a light sensor value of 10 to 2000 lux. When adjusted to the "sun" position (maximum lux value), it operates day and night; in the "moon" position (minimum), it operates when the ambient light is less than 3 lux. </span></li> <li class="a-spacing-mini"><span class="a-list-item">[Adjustable Delay] From 10 seconds to 7 minutes, you can set the delay time according to your needs. Delays are continuously added, and when the presence sensor mounted on the ceiling receives a second sensing signal after the first sensing, it recalculates the time again. </span></li> <li class="a-spacing-mini"><span class="a-list-item">【Adjustable Detection Sensitivity】Turn clockwise to increase the detection distance, and counterclockwise to decrease the detection distance. </span></li> <li class="a-spacing-mini"><span class="a-list-item">【Wide Application】Working by detecting infrared rays that detect human motion, the presence sensor mounted on the ceiling can be used in garages, corridors, basements, stairwells, kitchens, cloakrooms, attics... For indoor use, please install the presence sensor in a place away from direct sunlight and rain. </span></li> <li class="a-spacing-mini"></li> </ul>
