Motion Detector Lights
Motion Detector Lights


Motion detectors are tiny electronic eyes that detect infrared, or heat waves, emitted by moving objects. When the detector detects an object moving across its field of view, especially a warm object such as a person, animal or car, it electronically turns on the light. Motion detector lights are convenient, easy to use and cost effective. Millions of people use it inside and outside their homes. They are simple technologies that we take for granted.

Motion detector lights use special technology to detect movement and turn on the lights. Here’s a basic overview of how each type of motion detection works in the context of motion-sensing lighting. Some motion detection technologies use sensors to detect thermal differences. When the sensor detects a sudden change in temperature (eg when a body crosses in front of you), the light turns on. This type of motion sensor is best utilized for indoor motion detector lighting instead of outdoors.

Different type of motion detection technology detects blocked signals. Each time you pass in front of the sensor, it physically blocks the signal it emits, signaling that the light is moving and it’s time to turn it on. This type of sensor is suitable for both indoor and outdoor motion detector lighting. A light change detector tracks the ambient light and turns on the light whenever a sufficient light change is detected. These types of motion-sensing lights are typically used outdoors and are most often set to only activate when it’s dark outside, such as porch lights. Just by looking at the name, you can easily tell how the touch sensor works. Contact sensors, typically installed on doors or windows, are activated when a direct signal from one part of the sensor to another is blocked. This happens when a door or window to which they are fixed is opened.

Indoor motion-sensing lights can be activated when a family member walks into a room or when a curtain flaps in the wind. Air conditioners and heating units can also turn on lights when motion sensor lights are activated by heat. This can happen if the sensor is placed too close to the vent and this can be prevented by placing the temperature-activated sensor at least 15 feet away from the vent. Motion-sensing lighting installed inside your home increases convenience and reduces electricity bills. However, if the sensor cannot be installed in the correct location, motion detector lighting is less effective than manual switch lighting.

Outdoor motion-sensing lights can be activated by passing cars, approaching visitors, or the rustling of leaves of nearby trees. Sometimes a bug or spider crawling across the light sensor can turn on the light. People generally want outdoor motion detectors to turn on when they approach their home. To do this, sensors must be placed to cover sidewalks, driveways, porches and garage doors. For your backyard, you’ll want to place the sensor where you can see the back door, patio, and stairs. If there are areas that could be hazardous in the dark, such as swimming pools or hot tubs, take special care to place the sensor around those areas.
