What Are Energy Saving Motion Sensors?
Motion sensors automatically turn on lights and appliances when they detect movement and turn off after a period of time that you can set yourself.
How Do They Work?
Motion sensors have two common methods of operation: ultrasonic (sound detection) and infrared (movement and heat detection). Most household sensors use infrared technology.
Products like Lutron’s Occupancy-Sensing Wall Switch control the main lighting in a room.
This sleek, unintrusive motion sensor switch detects when someone enters a room and automatically turns the lights on, then detects once a room has been vacated and turns the lights off. An adjustable timeout function allows you to set the amount of time before the lights turn off.
Products like Lutron’s Radio Powr Savr Occupancy/Vacancy Sensor can be used to control up to 10 wall switches.
Easy to install and easier to use, you’ll never have to think about turning the lights on or off anymore, it will automatically turn on the lights when you enter the room and off after you have left. Since up to ten wall switches can be installed in conjunction with a single Radio Powr Savr Sensor, making your whole house energy efficient is a breeze!
How do they save money?
Every light and appliance that is left on when not in use is a waste of electricity and money; whether it’s kids, guests or simply inconvenience that keeps the lights on, unnecessary power use will eventually add up.
Where are they most useful?
Motion sensors have many handy uses in and around your home.
- Outdoor security lights that will turn on only when activity is detected, but turn off when they’re not needed.
- Any place where you might accidentally leave lights and appliances on for long periods of time. In low to medium traffic rooms, you might accidentally leave a light or appliance on for hours or even days (basements, guest rooms, closets, laundry/utility/storage rooms) without realizing it.
- Places where there is added convenience from not having to turn lights on or off, such as the garage.
Are they easy to install?
Occupancy sensors typically require little or no wiring. The above video provides great step-by-step instructions for many different motion sensors in less than three minutes! Of course, they need to be placed where they will be able to detect the occupants.
