Completely built-in the lighting fixture, the motion sensor utilizes Doppler principle and RADAR technology to detect moving objects at certain speed & reflection surface, and gives output control signals to achieve on/off control, 2 steps dimming control, or 3-step dimming control function.
A daylight sensor is also employed to set the threshold at which the motion sensor can be activated. With DIP switch, it is easy and accurate to select suitable detection area, motion hold-time, daylight threshold, stand-by dimming level, as well as stand-by period to fit for each specific installation. Very nifty feature to save energy when not needed.
