Irene in Tavares has an old motion sensor light in her carport but it was sensing the way it should be so we stopped by and ...

A motion sensor activates the light when it detects something moving within its field of view. Photocells work with a resistor that changes its conductivity based on how many photons are hitting it.

There's really not much to the motion sensor. The sensor shoots out an invisible light field that spans 100 degrees horizontally and 100 degrees vertically. Its blind spot is 180-degrees to its sides.

Do you really need a stand-alone outdoor motion sensor when all of Ring’s outdoor lighting products have one built in?
