Abstract

The objective of this project is to design an intelligent anti-theft system for backpacks. The system employs a magnetic sensor to detect unauthorized openings. When the zipper is moved, the system interprets this as a potential theft attempt and triggers an alarm. The user can disable the alarm using an RFID card, ensuring it is only active when desired.
