How Does a Motion Sensor Light Work - Step by Step Guide

Last Updated:
8 min read

A motion sensor light is a light that is triggered when it detects motion. It is like a regular light except, it is attached to a sensor that turns the light on when the sensor is triggered by movement. Motion sensor lights can be installed both indoors and outdoors.

When they are installed indoors, they can be fixed in doorways, ceilings, and walls. There are different types of motion sensor lights that you can choose from depending on your specifications, needs, and budget. As more technological advances are made, having a motion sensor light can be a great way to use less energy, take up less space, and have a high-security level.

How Does a Motion Sensor Light Work?

If you have ever gone in a room or were passing by a building and the lights suddenly went on, that was a motion sensor light at work. You can have a motion sensor light installed in your home or building for security purposes or because you would like your front porch to light up when you get home. 

A motion sensor light essentially operates by turning on the light when it detects motion, and the sensor turns the light off when motion is no longer detected. You will first need a motion detector or motion sensor to have a motion sensor light. 

There are different types of motion sensors you can choose from, such as: 

  • microwave, 
  • photoelectric, 
  • dual technology, 
  • active infrared, 
  • and passive infrared

Although motion sensor lights are usually turned on automatically, there are a few instances where you can manually turn on the lights. Essentially, as long as there is movement, the light will stay on and only go off when no motion is detected.


How to Adjust Motion Sensor Light

When you get your motion sensor light installed, ensure it has good coverage and that it can easily detect motion. Most motion sensor lights usually have sensitivity, time, and lux. So to adjust the sensitivity, locate the SEN sign on your sensor, here you can adjust and set how big an object is and how far away it should be for it to activate the sensor.

You can also do this by adjusting the minus and plus signs. You also have to set the duration you would like the sensor to activate by changing the plus and minus control signs. Lastly, the lux controls have a moon and sun picture since it is the night and day control setting.

When you move it towards the moon's side, it means it will activate when it's dark, and if you move it towards the sun's side, then it will be more active when it is lighter. If your area has street lights, this feature is quite essential since your motion sensor light may not activate at night if it's on the moon side due to the light from the street lights.

Therefore, have the time setting on the minimum and the lux (Light Level Adjustment) setting on day mode. Switch on the sensor control light switch, and have the sensor in the direction you want it to scan.

It would be best to do a test run once you have adjusted the setting to see if it works. You can adjust your motion light sensor where necessary. It is worth noting that when you adjust your motion sensor light, it would be best to do it during the period you would like it to be activated.

How Do You Install Motion Sensor Lights?

What you need to know when installing Lumenology motion sensor light or a standard motion sensor light:

Installation of standard motion sensor lights comes with all kinds of problems if you're not good with power tools and electrical. You would have to deal with a lot of wiring and drilling holes in the wall.

Lumenology, on the other hand, is simple to use. It doesn't require any wiring because it's battery-powered (3 AA batteries). You can attach it anywhere you would like since it comes with a flexible tripod and a magnetic base that uses only one screw. More on this later on...

To install your motion sensor lights, you will first need to turn off your power at the circuit breaker. Once you figure out what circuit belongs to the light switch you want to replace, that is the one you turn off. It may perhaps be a good idea to have a professional install the motion sensor light for you, especially if you are not confident with anything electrical. It is safer and prevents any potential accidents.

Next, you will have to test the wires before removing the switch. Take the wall plate off the switch and use a circuit tester to test the wires to confirm that there is no electric current still flowing in the wires you want to remove. Once you have confirmed that the power is off, you can remove the screws holding the switch in place.

Next, you will have to cut the wires on the old switch's back. You will see a bare ground, white and black wires connected at the back of the switch. Connect only the white and black wire to your new motion sensor switch.

Use a wire stripper to strip the white and black wires' plastic insulation at their ends. Connect the stripped ends to the new switch, then use your wire connectors to secure them.

Once you are done, tuck all the wires to the switch's back, then use a mounting screw to secure the switch. And lastly, do not forget to customize your controls.

What Kind of Problems Do People Face?

Installing regular lights can be quite a hassle. For instance, when you install a single light fixture, you may need to do extensive electrical work, which may not only add up to $500+, but it is also time-consuming, difficult, makes a total mess, not forgetting how unbelievably dangerous it is.


There are multiple other energy-saving wireless solutions that you could use, such as solar, but they are usually complicated to set up. They typically need the appropriate amount of sunlight, they do not retain charge for an extended period, and they also do not work indoors. This not only makes them an ineffective solution, but it also makes them quite limiting.

What is the Best Solution for Such Problems?

To solve such problems, think Lumenology. Lumenology is a lighting solution that can solve all of these problems because it is a portable lighting solution powered by 3 AA batteries.


You can easily attach it anywhere you would like in a matter of seconds, it is long-lasting, and it is also affordable.

Save Hundreds of Money


You will be able to save hundreds of money that you would have spent on getting an electrician. For instance, if you are a homeowner, then you know how expensive it is to hire an electrician.

You could also use it as a lamp by having it stand upright since it has a flexible tripod base included in each light kit. The tripod option allows you to use it as you would a conventional light.

It is also weather-resistant, which makes it perfect for both indoor and outdoor use. So whether it is raining or there is a heavy storm, your Lumenology light will still work.

Lumenology is a must-have item if you are looking to spruce up your patio, closet, workshop, attic, shed, or yard lighting.

You will have peace of mind because whenever someone takes the trash out, is walking the dog, is descending the staircase, or stepping on the patio, the lights will turn on. This can prevent any run-ins with danger and potential accidents. 

It has a motion-sensing technology that can detect both animals and people within one hundred-degree angle up to 13ft away. When it detects movement, the bright light will automatically startle and expose prowlers, which will deter destructive animals, package thieves, or trespassers.

Since the light is automatic, it may fool them that you are alert and aware of their presence, when in a real sense, you may not even be home.

It would help if you attached your light on your exterior wall's surface, trees, above the garage, and even on your roof's eaves. You can also have it cast a wide beam of light on the backyard fence entrance or the main walkway.

Getting a motion sensor light is the best security decision you can make for your home and building.
