How to Trick a Motion Sensor to Stay on

Motion sensors are a helpful tool for lighting because they turn on and off lights as you need them. However, if your motion sensor is acting up, it can be frustrating to have the light come on when you don’t need it or not come on when you do.

In this blog post, we will cover how to trick a motion sensor to stay on. Most motion sensors use infrared technology, which means that if there isn’t an object in their path, then the light won’t turn on.

How to Trick a Motion Sensor to Stay on

Place any small object between the sensor and its target area to trick a motion sensor into staying on. The presence of this simple object will keep the light from turning off until that item is removed from its space between the two devices. Unfortunately, this simple trick works only if you have a single on/off motion sensor. Read on to know more information!

10 Ways on How to Trick a Motion Sensor to Stay on

1. Use a Piece of Aluminum Foil:

Take a piece of aluminum foil and create a small pocket in the middle of it. Then place your hand in the pocket to track the motion sensor into thinking that someone is there. This is an excellent trick if you’re looking to make your home look like it’s occupied when it’s not.

2. Use a Glow-in-the-Dark Ball:

The light from the glow-in-the-dark ball will trick the motion sensor into thinking that there is a person nearby, preventing it from turning off. This is an easy way to make your home look occupied without spending any money.

3. Use a Spoon:

A widespread and easy trick is to drape a spoon on your hand. The light from the motion sensor will fall on the back of the spoon and reflect onto your hand, which will look like its emitting light. This can fool some motion sensors into staying on even if you’re not nearby.

4. Use a Nightlight:

This is an excellent trick if you want to save money and don’t mind that the nightlight will be on when it’s not necessary. Plug in a motion-sensing nightlight in your home when nobody is there, then plug it out when people are around. This will make your home look occupied even during the day.

5. Use a CD Spindle Piece:

The light from the motion sensor will reflect off the reflective side of the cd spindle piece and create a small glowing ball that can look like people walking back and forth. This is a low-cost way to trick your motion sensor into thinking there are people around.

6. Use a Fake Pet:

Most motion sensors detect heat signatures which means that they should be able to pick up on the same heat signatures as your pets. So, for example, if you have a pet bird, put it in its cage when you’re around but take it out of the cage when nobody is home to trick your motion sensor into thinking that someone’s in the room.

7. Use a Fake Spider:

An easy way to trick the motion sensor into thinking there’s a spider in your home is to get a fake toy spider and move it around occasionally. This will make your motion detector believe that spiders are crawling around, which will keep the lights on for a longer time.

8. Bypass the Motion Circuit:

This trick is risky and should only be done if you need the light to stay on. There’s a wire going from the motion sensor into your fuse box; cut this wire so that it doesn’t go back. This will allow the light to stay on even when there aren’t any people around, which can be great for walking through dark hallways.

9. Use Newspaper Clips:

This is an easy way to make your home look like it’s occupied without spending any money other than what you would spend on newspaper clips. Clamp the newspaper clip onto your hand and place it over the motion sensor; this should trick the sensor into thinking someone is walking around.

10. Use a Security Light:

If you have an outdoor motion sensor, get a security light and place it above or near the motion detector; this will make the sensor think that someone outside will keep it on for a more extended period. This can be useful if you leave your backdoor open at night.

Five Advantages and Disadvantages of Motion Sensor


1. Motion detector will help you feel safe in your home, even when you are sleeping.

2. It can save you money because it will turn off lights when no one is using them, reducing electricity costs.

3. Motion detectors are great for security purposes since they help you feel safer in your home.

4. One of the most important advantages is that motion sensors will activate light switches that are not wired to lights. For example, in a hallway or stairway where one doesn’t want lights to burn all night long.

5. They will turn on when you enter the room and shut off when you leave, so it feels like there is someone home even if there isn’t anyone living in the house at the moment; because of this, they are a great way to scare burglars.


1. Motion sensor will shut off when movement stops, leading to unnecessary power consumption.

2. Sometimes, motion sensors are too sensitive, like in the case of lights near windows (or doors), where the wind blows by and turns them on constantly, or if one walks very closely underneath it.

3. The motion sensor doesn’t detect slow-moving objects, so it might not turn on when walking in front of the sensor.

4. Motion sensors will shut off if direct sunlight falls on it or reflects from a shiny surface, like mirrors.

5. When setting up motion detectors, you have to be careful with angles and distance from one another; otherwise, you could end up with the lights turning on behind something instead of in front of it.

Things to Consider When Using a Motion Sensor

1. Always place your lights on a timer, so the lights turn off after a short amount of time.

2. Install lamps near frequently used areas, so you’ll never have to venture into the darkness.

3. Keep all small pets in view; most animals know that they are not supposed to enter an area with motion detectors installed, but some kinds of birds and rodents are naturally curious by nature.

4. Place lights that will turn on after a few seconds or minutes, rather than keeping the lights off all day and night; this way, your light usage won’t be significantly affected during daylight hours.

5. People can use motion sensors to their advantage; for instance, installing motion detectors on the front porch or near an area where vandalism is common can act as a deterrent.  

6. If there are people in your household who like to sleep all day long, it may be best to install multiple lamps that turn on and off at different times; this way, you won’t disturb them while they sleep.

7. The placement of motion sensors is essential; the area covered by a motion sensor should be as small and specific as possible (for example, don’t place it where it will turn on every time you enter the room).

Can You Override a Motion Sensor?

Motion detectors use infrared technology to sense movement in an area. When the sensor “sees” something move, it sends out a beam of light. If something gets in the way of that beam, like a person or animal, the motion sensor has its built-in light source and breaks the beam, so it doesn’t send back any signals.

use infrared technology

That’s how it knows to switch on an attached light. Some motion detectors use other forms of technology, but the principle is still the same. When movement is sensed, the sensor sends a signal to activate whatever it’s attached to. Motion detectors are often used in places where energy conservation is important, like outside lighting or parking lots.

They can also be found in some homes, usually for security purposes or when an owner wants to conserve energy by only turning on lights when people are around. You wouldn’t want lights staying on in an empty room, for instance. Reading this full blog post will benefit you if you want to know how to trick a motion sensor to stay on.


If you have a motion sensor that doesn’t work or want to keep it running all the time, there are a few methods for tricking your sensors. The first is by using an infrared emitter and receiver pair, which can be plugged into any power outlet.

This will emit a signal just like natural light to fool the sensor. Another method is to use adhesive tape with two pieces of electrical tape on each side to cover up the light receptor from sensing movement at night when no other lights are being emitted.

Finally, if none of those tricks worked for you, try installing some LED lamps around the area where your motion sensor would usually be triggered and then turn them off during daylight hours (or install timers).
