This is a home security system project that uses laser light and a light sensor LDR. A security system is used to protect our homes, offices, banks, lockers, etc from unauthorized persons. Different types of security systems available and a laser-based security system is also an important and efficient type of Laser light security system.

If the beam is interrupted anywhere between the laser and the detector, the electronics will put the warning signal. PRINCIPLE: There are three essential components to a Laser Security Alarm System: a laser, a detector and sensing circuit. The laser is a concentrated light source that
Thus, we have designed a home security alarm system using Arduino and PIR motion sensor, which is handy, portable, cost-effective and highly effective as well. Such alarm systems are hugely in demand for security purposes, and thus the given system can be proved useful and effective in view of the above features. FUTURE SCOPE There are many kinds of anti-theft alarm systems. One such system can be made using Light Dependent Resistors (LDR). An LDR based alarm system can be used to protect lockers or locker rooms. In such a system, the LDR sensor is attached to an alarm mechanism and a light source or laser light source is fixed above the sensor in a closed casing.
