Use it on doors to light up entrances automatically at night. Use it under the kitchen cabinets to light up only when there is movement and darkness. The sensor includes 2 connection cables (40”) that connect between the power source and the LED light bars. There has to be a minimum of 10 lux for the light sensor to cut the lighting. If there is ambient light it will not turn on the lights even if it detects movement.

Also it includes a Light sensor that will detect if there is ambient light. Once movement is detected, the sensor will power on the Premium LED light bars for about 30 seconds. The motion sensor has a passive infrared detector (PIR) that will detect any movement on a 6 to 9 foot range and an ambient light sensor that will control if the lights are power up or not, depending on the ambient lighting. Solid Apollo’s Motion Sensor with light sensor is designed to be used with the Premium LED Light Bars and LED puck Lights.
