Laser Control Switch

Abstract

Normally remote control performed with either modulated infrared emitters or radio-frequency wireless transmitters. But now a day, not only infrared emitter and radio-frequency wireless can be use as transmitter. Lasers also could play an important role in technique of remote control. It could control the electronic device such as lights or the fans by simply aiming the laser dot at the correct spot on the desired object, without walk to the switches. The objective of this project is to make comparison between the laser control switches with the ordinary mechanical on-off switches and make the conclusion which is the useful switches. This type of laser control switch was special design for the huge building so that it could made easier the process switch ON or OFF of switches and this module of switcher also can made the lower of cost building.
