Installing Motion Detector Sensors for Outdoor Lighting
Electrical Question: Does anyone make a recessed can light for outdoor use that has a motion sensor?
- Or how do I add a motion sensor to an outdoor recessed can light in the ceiling of my porch?
This electrical wiring question came from: Chris, a Homeowner from Aubrey, Texas.
Additional Comments: Great Site!

Thanks for your electrical wiring question Chris.
How to Control Your Outside Lights with a Motion Detector
Application: Wiring Outside Lights that are controlled by a Motion Detector.
Skill Level: Intermediate to Advanced. This electrical wiring project is best performed by a Licensed Electrical Contractor or Certified Electrician.
Tools Required: Basic Electricians Pouch Hand Tools, a Voltage Tester and a fiberglass ladder.
Estimated Time: Depends on the personal level experience, ability to work with tools and work with the outdoor light circuit wiring.
Precaution: Identify the panel circuit for the outdoor lights, turn it OFF and Tag it with a Note before working with the wiring.
Notice: Modifying or installing additional electrical wiring for outdoor lights and lighting controls should be done according to local and national electrical codes with a permit and be inspected.
EXAMPLE #1
Wiring a Motion Detector to Control Outdoor Lights
- Motion detectors can be purchased and used to control just about any type of lighting.
- The only limitation will be the number of lights that will be controlled by the motion detector.
- If the lighting load exceeds the watts limitation of the motion detector, then simply use the motion detector as a switch to activate a relay that would then control the load of the lighting circuit.
- Multiple motion detectors may be installed to control lights from various locations as long as the control wiring is configured properly.
- NOTE:
- Multiple motion detectors can be wired to control the lighting fixtures for a staircase that has multiple levels.
- The motion detectors act as a switch which controls a relay.
- The circuit components and wiring must be sized according to all the devices that will be installed.
EXAMPLE #2
Wireless Method for Controlling Outdoor Lighting
- Wireless Motion Detector Yard Light
- I have a hard wired Heath Zenith switch in the garage and another at the back door with the wireless motion detector on a post in the back yard. You can turn the lights on manually from each switch or else they will come on automatically when activated by the motion detector. I haven’t found another product where the motion detector is battery operated and wireless.
- The only limitation is that you can’t use these switches with CFL bulbs, even the dimming ones. I’d like your opinion on this idea:
- I would like to use a relay to operate as the light fixture switch control.
- When the Heath Zenith switch is turned on manually or automatically by the motion sensor the relay would be energized and then the CFL lights would be controlled by the relay.
- Would that work?
- Using CFL Lamps for a Motion Detector Light Fixture
- Using a relay to operate outdoor lights will enable you to use CFL lamps as long as the lamps are rated for outdoor use.
- As described in this question, the circuit of the wireless control does not allow the CFL lamps to be used, so by using a control relay this may be a good solution.

Be Careful and Be Safe - Never Work on Energized Circuits!
Consult your Local Building Department about Permits and Inspections for all Electric Wiring Projects.
The Safest Way to Test Electrical Devices and Identify Electric Wires!The Non-Contact Electrical TesterThis is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
The Quickest Way to Check for Faulty Electrical Wiring!The Plug-In Outlet TesterThis is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring. It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.
Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!The Wire Stripper and Wire CutterMy absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires. This handy tool has multiple uses: The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation. The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets.. The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use. |
