How to Install a Motion Sensor Light Switch

Motion sensors are great at saving energy and bringing convenience. They can automatically turn on the light for us when detecting motion from a person and turn off the light for us when no motion is detected. Whether it’s outdoor or indoor usage, a spínač světla se snímačem pohybu is better than a mechanical light switch in most cases.

Motion sensor light switches are great at saving energy and bringing convenience to our home. The motion sensor detector can automatically turn on the light for us when we enter the room and turn off the light after we leave. A motion sensor light switch is more preferred than a motion sensor light for home use because we need to manually take control of the light most of the time. And it’s easier to simply upgrade the traditional wall switch with a motion sensor light switch than to replace the light fixture.

It’s never too late to replace your manual mechanical light switch with a smart, motion-activated one, and wiring and installing a motion sensor light switch can be fast and easy.

You don’t need to call an electrician for the job. All you need is some common tools like a screwdriver that every home has (you don’t own a screwdriver?) and within 30 minutes, you can get the job done even for beginners with no electrical knowledge.

Step 1. Prepare tools for the installation

Before we install a motion sensor light switch, prepare these tools first so we can speed up the process.

• A motion sensor light switch
• Šroubovák
• Volitelně
  • Drátové nůžky: v případě potřeby k přestřižení drátů
  • Drátové konektory: většina spínačů se snímačem pohybu standardně obsahuje v balení příslušenství drátové konektory.
  • Voltage tester: to identity the hotwire and ensure the voltage is off
  • Elektrické pásky: k označení horkých vodičů

Step 2. Remove the Old Switch

Turn off the breaker to the light you want to replace the switch of and turn on/off the existing switch several times to ensure there is no power.

Now we can safely remove the old switch. Suppose you have absolutely no electrical knowledge and worry about the wiring. In that case, you can take a picture of the existing wiring to apply similar wirings to the motion sensor light switch or even restore the old wiring and the switch.

Mark the hot wire(the black wire) with electrical tapes if necessary.

If you do not know which is load wire or hot wire, use the voltage tester to confirm with the following process:

1. Turn on the breaker
2. Move the voltage tester near each black wire
3. The hotwire has power and the load wire does not have power
4. Turn off the breaker
5. Use the voltage near the hot wire to ensure the power is off
6. Mark the hotwire with electrical tapes

Step 3. Wire the Motion Sensor Light Switch

First, make sure the breaker is turned off and there is no power with a voltage tester.

Now we start wiring the motion sensor light switch to the light by connecting the wires with the same color.

• Hotwire(black) to the light switch’s hotwire(black)
• Load wire(black or red) to the light switch’s load wire(red)
• Connect all neutral wires together (white)
• Connect all ground wires together(green or bare copper)

Now we partially screw the motion sensor switch into the wall box and test the wiring.

Turn on the breaker and the motion sensor light switch needs some time to warm up and will automatically turn on the light if the wiring is correct.

Press the buttons on the light switch to see if you can successfully control the ON and OFF of the light.

Step 4. Fix the Switch Into the Wallbox

Strengthen the screws, install the cover plates, and adjust the switch to a straight position.

Now you can adjust the functions of the motion sensor light switch to a proper setting according to the user manual, such as occupancy sensor and vacancy sensor motion detection mode, time delay, and ambient light sensing.
