There are many fields of science where they use motion sensors. They use them to make house alarms, spy things etc. However, they never thought of using this technology in a usual house so that the families would benefit from it until now. My husband told me about this electronic gadgets and he said that we should install them in our house.
The idea is when you enter the room you do not have to turn on the light it will do that itself. You don't have to enter the dark basement and look for a switch anymore. Besides, it is very convenient when you have your hands full of something.
This sensor looks like a usual bulb fixture and you just put in the bulb right into it. It is not very big and it has a height of 4 inches and the width of 3 inches so it is not much bigger then a usual bulb. Its radius is 12' and this means that it will work fine in most of the rooms except the really huge ones but I think it is enough for those rooms where you would like to install them.
The motion sensor covers all the 360 degrees around so be sure it will not miss you coming in. This electronic gadget can light up a bulb up to 100W one. It is very handy to have a gadget like this in my home because it really helps me a lot.
