Door Safety Alarm Using IR Sensor– Science Hobby Project
Abstract: The Door Safety Alarm Using IR Sensor is a simple and effective security system designed to detect unauthorized entry or movement near a door. The system utilizes an Infrared (IR) transmitter and receiver pair to create an invisible detection beam. When someone opens the door or interrupts the IR beam, the system instantly triggers an alarm, alerting the user to potential intrusion. This project offers a low-cost, reliable, and easy-to-implement solution for enhancing security in homes, offices, shops, and restricted areas. It demonstrates the practical use of IR sensing technology for real-time monitoring and provides an efficient method for preventing theft, unauthorized access, and safety breaches.
Applications:-
- Home Security Systems- Detects unauthorized entry through doors and triggers an alarm.
- Shops and Commercial Stores- Alerts shopkeepers when a customer enters or someone tries to access restricted areas.
- Offices and Workplaces- Monitors entry to sensitive rooms like server rooms, cabins, or inventory areas.
- Banks and ATMs- Enhance security by detecting unauthorized access to doors or safes.
- Schools and Colleges- Used for monitoring lab rooms, staff rooms, and restricted zones.
- Hospitals- Ensure safety in medicine storage rooms and emergency wards.
- Warehouses and Storage Units- Protects valuable goods by sensing unauthorized opening of doors.
- Hotels and Guest Rooms- Acts as an additional layer of door security for guests and staff.
- Parking Areas & Garages- Triggers an alarm when someone enters without permission.
- Smart Home & Automation System- Can be integrated with IoT devices for notifications and remote monitoring.
