How Do Motion Detectors Work? Motion detectors are small electronic eyes that detect infrared waves, i.e. heat waves that radiate from moving objects. When the detector senses an object moving across its field of view — especially warmer objects such as people, animals and cars — it electronically turns on the lights.
Do sensor lights need special bulbs?
Motion sensor lights require occasional maintenance when the bulbs burn out. Fixing the problem is simple, because all you need to do is replace motion bulbs with new light bulbs.
What triggers sensor lights?
Outdoor motion detection lights can be activated by passing cars, approaching visitors, or even rustling leaves in nearby trees. Sometimes bugs or spiders that crawl across your lights’ sensors can even trigger your lights to turn on.
How do you trick a light sensor?
Often, the wind blowing through leaves and branches can cause the motion sensor to detect motion, causing the light to stay on. Turn off the switch which operates the motion sensor light. Keep the switch off for 1 to 2 seconds and then turn the light switch on again.
Why is my sensor light not working?
If the light won’t come on after adjusting and cleaning the sensor, try a simple trick. Turn off the circuit breaker that controls the light circuit and leave it off for 30 minutes. … If the light doesn’t come on when you turn the breaker back on, try replacing the bulb. If that doesn’t work, the sensor may be bad.
Can you put a motion sensor bulb in any light?
A remote-style motion detector is a better choice. You can connect it to any type of decorative fixture—even existing ones—and mount it discreetly off to the side. … The toughest part of this project may be running the wires that connect the sensor to the light fixtures.
Will motion sensors work with LED lights?
The answer is yes. LED lights can work with motion sensors with the right configurations. A lot of lighting technologies today make use of motion sensors attached to LEDs.
How do you reset a sensor light?
How to Reset a Motion Sensor Light
- Turn off the fixture’s circuit breaker for at least 30 seconds.
- If the fixture has a light switch, turn the switch on for 2 seconds, then off for 2 seconds, and then back on.
- If the fixture has a light switch, quickly switch it on and off four or five times, or until the light stays on.
Do motion sensor lights work during the day?
Some units combine motion sensors and light sensors, but their photocells don’t turn the lights on when the sun goes down. When paired with motion detectors, photocells keep lights off during daylight hours. … You can also adjust these fixtures to allow the motion sensors to work all day.
Can moths set off sensor lights?
Insects and small animals set off PIR motion detectors because they emit the infrared (IR) energy needed to activate the devices. If an insect or small animal gets close enough to the sensor, then they will be able to activate it.
Can you make a sensor light stay on?
Most motion detectors have a built-in override: Normally the switch is kept on all the time. … If you turn the switch off and on within a second or so, the light will stay on, and this overrides motion detection. To go back to normal operation, turn the switch off and wait ~10 seconds, then turn back on.
Can you trick a motion sensor?
Most motion detectors, even newer ones, use infrared to detect significant changes in the surrounding room’s temperature, Porter said. Normally, walking around in a room would set off these sensors, but using something as simple as a piece of styrofoam to shield your body can trick them, he said.
Do motion sensor lights use more electricity?
In order to respond to movement, these light switches are always on standby and thus consume some amount of phantom energy. So unless you’re forgetting to turn off your 60-watt light bulb 14 hours a day every day for a year, the cost of purchasing and powering the standby light switch isn’t worth the investment.
How do you test a light sensor?
How to Test a Light Sensor
- Look on the bottom of the light sensor to find its slide switch and sensory adjustment dial. …
- Flip on the wall switch to send power to the light sensor. …
- Position the sensor to face the direction you want motion detected. …
- Walk across the detection zone where you desire the light sensor’s response.

Do outdoor light sensors go bad?
Whether your post light is 120-volt, or low-voltage, most lights have a dusk-to-dawn sensor in the post (a small round “eye”). Many times, this can go bad, causing the light to stay on or off, regardless of the time of day. A sensor for a 120-volt is easily replaced and available at hardware stores.
How do I get my motion light to work?
To reset most motion detecting lights, shut off the power supply at the switch for at least 30 seconds, making sure there’s no motion in front of the sensor during this time. Then turn the light back on and test it to ensure proper function.
