Laser Security System Using IOT

Abstract

 In this era security is major issue for home environment and home security system is very essential these days as intrusions are increasing year after year. We should use latest technologies as thieves are also getting smarter, they now know how to break locks. We need a security system that is satisfactory in terms of security as well as cheap. In recent times many organization invested a lot in home security systems. This paper deals with design and implementation of “Laser based security system” which uses laser as a mean of catching or detecting intrusion. LDR (Light dependent resistor) is the main component of this system as it detects the intrusion in the laser which then further sends signals and alert the owner. The second major component of this system is Arduino which is be used to inform the owner about the intruder with an alert. It is hidden security system that intruder would not be known about as laser is not visible within the air and it only be giving light on LDR. This system is one of the efficient and cheapest security system that can be used anywhere not only in homes.
