The The Photon Sentinel: A Light-Dependent Security System for Domestic and Professional Environments

Abstract

Security in one's home has always been a worry. Numerous home-based security systems have been created and put into place to protect their welfare as technology develops at a rapid pace. A crucial tool for preventing unauthorized entry into our homes is a home security system. In this study, we introduce a security system that can be applied in both private and public settings. The proposed system measures the light intensity with a light-dependent resistor (LDR). The LDR sensor measures the brightness, produces a theft alarm, and illuminates the area. It is an easy-to-use, cost-effective, convenient, and reliable security system for room lockers in residences and offices. For urgent security, the buzzer alarm is necessary. The circuit was created on a breadboard and tested in various lighting settings. As a result, the system can accurately detect variations in light intensity and correctly activate the output devices. This cutting-edge security system can offer a workable, cheap solution for a variety of security applications.
