The L1 is for load wire which powers the lights. The L is for line wire or hot wire, which is the power source from your house. The wiring is pretty straightforward, similar to installing a motion sensor light switch. This is a standard motion sensor wiring diagram and you can apply nearly all wirings like above. Wire the Motion Sensor to the Light The wiring of a typical ceiling motion sensor Mark the hot wire with electrical tapes if needed.Turn off the power and use the non-contact voltage tester to confirm.The hot wire has power but the load wire to your light does not have power. Turn on the power and use the non-contact voltage tester to test each black wire in the junction box.
INDOOR MOTION SENSOR LIGHT SWITCH WIRING DIAGRAM INSTALL
Install a junction box and cut the hot wire and neutral wire for installing and fixing the motion sensor, if needed. Find a place where you want to install the motion sensor between the power source from your house to the light. Turn off the power to the light which you want to add a motion sensor to.

In this case, a ceiling mount motion sensor or a standalone motion detector located on the wall, which can detect people from up to a 360 degree with a larger sensitivity zone, can perfectly solve our problem.Īnother benefit of adding a motion sensor, i.e., a occupancy sensor, to your existing light is that you can have automatic ON/OFF lighting, which is completely hands-free and suitable for public rooms and offices. Sometimes we need to detect motion from a broader coverage where a motion sensor light switch is incompetent with the restricted detecting area on the wall.
