DIY - Lighting – Motion Sensors for Home Lighting

One of the latest crazes in home lighting is the use of motion sensors. But there’s nothing crazy about this craze. It makes perfect sense. Whether used for security or convenience, motion sensors can add a very useful high-tech touch to lights both outdoor and in.

The most obvious application, and one in wide use today, is to turn on outdoor floodlights when anyone approaches within the sensor’s range. Studies confirm common sense that a well-lit home is less vulnerable to a home invader than one that has large dark areas near points of entry.

Adding motion sensors and/or motion sensor lights is an effective way to solve that problem. They trigger the lights on approach, which has two advantages. A light that comes on unexpectedly tends to startle the unwanted visitor. That provides extra motivation to change their plans and move on to an easier target. Homeowners also save money on electricity by not having high-wattage bulbs burn all night long when and where they’re not really needed.

That goal can be accomplished with separate motion sensors that are connected to a whole system, one that includes lights, a horn or other security components. Or, as is the case in many fixtures, the motion sensor can be integrated into the lamp housing itself. Both are effective, though in some cases separate motion sensors have a greater range and angle of coverage.

But security isn’t the only reason that motion sensors can be a huge benefit. They can supply extra safety and convenience, as well.

You pull up into the driveway or walk outside on a dark night. You can’t see a thing. That toy or bicycle is just waiting there for you to step on. That low garden fence you always forget about is ripe for bumping into. Motion sensors can turn on the lights at your approach and prevent accidents.

They can also make it much easier to turn on the lights when you just need a brief light. You don’t have to be near the switch, you just approach or wave an arm and on pop the lights. Now you can find your keys, put away that pesky toy or just make it into the house without any trouble.

Many of the same considerations apply to indoor motion sensors, too. But indoor sensors come in an even wider variety of types and styles.

Existing wall switches or outlets can easily be converted to contain motion sensors. That makes it very easy to have a system that turns on the light when you enter, then turns it off when you leave.

Motion sensors can be integrated with hallway lamp sconces to provide illumination when you enter. You save electricity and bulb life by having the light not on when you’re not there.

Look into the full range of motion sensors available: wireless, infrared, ultrasonic, weatherproof and many more.
