Driveway Motion Detector

I have a switch inside that controls the entry and four outside
entrance lights. How to wire a motion sensor in this circuit?

YOU WANT TO SPLICE in the line between the switch and the room lights. YOU must decide where you want PLACE OF THE PROPOSAL AND DECTER to place her son in and return to the lights. THE PROPOSAL DECTER is just another switch that WORK PROPOSAL. This would be a piece of cake to DO.

All you have to do is to buy a fixture that has a motion detector built it-I have one in the back of my garage like that. Flag

Buy one and read the instructions.

If the area covered by fires is low, the motion sensor must be connected to the first light from the switch with the son of supply of light (from the switch) is linked to the motion detector . The son of the load detector are then joined with the son of light and the son going to the light just below the line. It will control all the lights with a sensor.
Potential problems may be:
If the first light on the porch (which is likely), the motion detector will activate if someone approaches the terrace and is consistent with the area controlled by the sensor. It will not provide security in areas distant from the veranda.
If you want to ensure safety in all areas (in the case of a supermarket), you'll need to install sensors on more than one light or every light. The wiring is slightly different for that. In this case, you must add the motion sensor on the line each and every son to tie light load side of the probe. (The side of the line is for the son of supply and load side is for the son of the fixture.)
