Abstract: This paper presents the design and implementation of a smart door unlock system that integrates face recognition, RFID authentication, IR-based exit detection, and an emergency override mechanism. The system is developed to address the limitations of traditional lock-and-key mechanisms, which are prone to duplication, loss, and lack of real-time monitoring. The proposed solution leverages Raspberry Pi camera module for image processing, RC522 RFID reader for card-based authentication, and an IR sensor for automated exit detection. A servo motor is used to control the door lock, while an emergency push button ensures accessibility during critical situations. The system is supported by a centralized admin panel that manages users, logs access events, and provides real-time monitoring. The prototype demonstrates cost-effectiveness, scalability, and practical applicability in residential, institutional, and industrial environments. Experimental results show reliable authentication, quick response time, and robust performance under varying conditions.
