The perfect mother's day gift. SmartHome is offering a very easy and affordable way to have motion-sensing lights in your house. The Screw-in Motion Sensor Switch is the thing you need if everybody at home seems to turn into deaf mules when mum asked them to turn on the lights.

From it's name alone, you may get the gist of this contraption. All you need to do is screw the motion-sensor into the light socket, then plug the light bulb into the motion sensor, you then don’t need to control the lights with light switches anymore as the fixture does it for you.

It features a full 360 degrees field-of-view so no matter where you enter the room from you should be automatically greeted by light. It also has a 12′ range so it could cover most room sizes. The light then stays on for four minutes after it detects the last motion. This is good and all that, unless you have pets who aimlessly wander around the house, then maybe you could expect your electric bills to go up a little. It will cost you roughly $30.
