Abstract - This paper introduces a security system that
friendly, ensuring ease of installation and use. This approach makes advanced security accessible to a broader audience, providing peace of mind to home and business owners alike.
combines a Laser Beam Alarm with an Automatic Door Lock System to enhance security in residential and commercial environments. Leveraging the integration of cutting-edge technology, this research explores the deployment of laser sensors and automatic locking mechanisms to detect and prevent unauthorized entries. This enables control and ensuring a comprehensive and responsive security solution. Extensive testing has proven the system's efficiency in intrusion detection by instantaneously activating alarms and door locks upon any security breach. This study details the design, functionality, and testing outcomes of the system, underscoring its potential to redefine security measures for large-scale protection against unauthorized access. By merging technology with traditional security tactics, this Laser Beam Alarm System with Automated Door Lock System presents an innovative approach to tackling modern security challenges.
2. LITERATURE SURVEY A few reviews were done in the past as part of research papers on: The first system involves a Home Automation Security system with Laser Lights Alarm designed for large spaces like factories to improve security. It utilizes Raspberry Pi controllers, laser beam modules, PIR sensors, and alert lights to detect intruders, sending alerts to mobile users and web pages. The system successfully sent and received messages and requests during testing. The second system is a wireless security system controlled by a wireless remote or touch-tone phone, featuring infrared motion sensors and an alarm unit triggered by detecting human body heat. It uses two types of laser beams: a green visible beam and an invisible infrared beam to enhance security measures.

1.INTRODUCTION In today's world, the need for effective security measures has never been more critical. With technological advancements, those with malicious intent have found new ways to breach security, posing challenges to traditional security systems. Consequently, there is an urgent need for innovative solutions that keep pace with these advancements. Individuals and organizations alike are on a continuous search for better and more reliable ways to protect their premises.
The third system introduces a LASER-based smart security system focusing on detecting burglars using imperceptible laser rays at entry points like doors and windows. Once the laser beam is crossed, the alarm is triggered continuously until manually turned off. This cost-effective system sends a photo of the intruder to a registered email address for verification, utilizing components like Arduino, LDR module, WIFI module, and a buzzer for alerts.

To address this need, we have developed a new security system named the Laser Beam Alarm System with Automated Door Lock System. This system utilizes laser technology to safeguard areas against unauthorized access. The principle behind this system is straightforward: if an unauthorized individual attempts to enter the protected area, the laser detects this activity. Immediately, an alarm is triggered to alert of the intrusion, and doors automatically lock to prevent entry. Lasers provide a precise and reliable method for detecting intrusions, significantly reducing the likelihood of false alarms—a common issue with other types of security systems. Moreover, we designed the system to be user-

When the system is activated, the laser diode emits a continuous, invisible laser beam across the entrance or area to be monitored. This beam is aimed directly at an LDR (Light Dependent Resistor) sensor placed on the opposite side. The laser diode and LDR sensor are crucial components; the diode serves as the source of monitoring light, while the LDR sensor acts as the receiver, changing its resistance based on the light intensity it detects.
