motion sensors see by sending out waves and timing how long it takes them to get back, when this time changes ( like someone stepping into a room) the motion sensor can tell that motion has been detected

Motion sensors can be bought from a wide range of retailers. Many retailers have online websites where you can easily buy the sensor, for example Wickes or Amazon.
There are more advantages than disadvantages to using a motion sensor light outside of your home. The biggest disadvantage is that the light will come on if an animal walks past it. Some of the advantages include knowing when someone is walking around your house and the light coming on for you when you get home and it is dark outside.
Optical sensors convert light, or changes in light, into electrical signals. They are used in products such as automatic lighting and flashes for cameras.
Sensors are used to detect things, such as motion, light, or color.
Motion sensors and surveillance cameras are used in basic security surveillance.
No. Proximity sensors are generally used to detect objects, not people. Motion sensors use a different technology.
Outdoor motion sensors allow a greater degree of home security. Motion sensors can be installed that can turn on outside lights when movement is sensed, or begin recording from a closed circuit camera.

Laser sensors are generally used to detect motion. They can be used as a safety device to protect something like a car hitting a wall. They can also be used to detect measurement and alignment and are widely used in medicine and industry.

There are no motion sensors in the Xbox 360 controller.
The ipod touch is the only one with a motion sensor.
