This project involves the development of a Door Alarm Buzzer System to improve security in school dormitories where theft is increasingly common. The system uses components such as transistors, diodes, relays, magnetic switches, terminal blocks, a 9V battery connector, and a switch to detect unauthorized door openings and activate a buzzer. Research was conducted through surveys and questionnaires to identify user needs. The project successfully reduces theft and enhances safety. Future improvements include adding wireless alerts, integrating motion sensors, and using rechargeable or solar-powered batteries to ensure continuous operation and efficiency in preventing unauthorized access in residential areas.
