Making Sense: How to Install a Motion-Sensing Light Switch

Carley Knobloch installs a motion sensor switch

A little light in the right place at the right time can mean the difference between a safe trip to the garage and a visit to the hospital. And when it comes to our parents, we all want to ensure that their home is safe and takes care of them like we would. Little changes and additions from the world of Universal Design make this possible.

In this episode of Smart Simple Solved, I swap my parents’ garage light switch with a motion occupancy sensing switch: Simply put, if you enter a dark room, the lights come on, and even if you’re standing still (or sitting on the couch, reading) it knows you’re there and doesn’t shut off until you’ve left. This is a great solution for rooms where the switch is tough to find in the dark, or rooms like the laundry room where hands are often full when you enter, and it means that rooms are always well lit, and arthritic hands don’t have to mess with switches.

Best of all, this is an easy DIY— in 15 minutes, you’ll have a smarter home, and a cheaper energy bill too.

Side note: My switch was a Single Poll Switch (that means only one switch turns this light off and on), so if yours is too, these instructions will work. If yours is a 3-way Switch (two switches turn the same light on and off) then the instructions are only slightly different, and you’ll want to watch this great video for extra help.

Step 6

Now’s a good time to customize the settings, before the wall plate is on. Follow the manufacturer’s instructions to tell the switch how long to leave the lights after the last person leaves (the “time out”), and get the motion sensitivity just right.

    If it is a dimming switch, you would need to look for dimmable fluorescent or LED bulbs. Regular fluorescent bulbs cannot dim

    will this work with the eco friendly light bulbs?
