The motion sensor detects whether someone enters a dark room or leaves a lit room. In the first case, it activates the light with the brightness and color temperature you have programmed. So, for example, if the children need to go to the bathroom at night, they won't be blinded by harsh light but will be gently guided through the corridors by soft lighting. In the second case, when someone leaves a room and no one else is moving there, the sensor gradually dims the light by 50 percent before turning it off completely.
