Smart Door Unlocking System Using Fingerprint Recognition

This paper presents the design and development of a smart door unlocking system using fingerprint recognition. The primary objective of this system is to enhance domestic security by integrating biometric authentication. The system employs a fingerprint sensor module to capture and verify user fingerprints, interfaced with a microcontroller for real-time processing. The unlocking mechanism is activated only upon successful fingerprint authentication, ensuring a robust layer of security. The system is designed for low power consumption and cost-effectiveness, making it suitable for household applications. Testing of the prototype demonstrated a high accuracy rate in fingerprint recognition and minimal response time, highlighting its efficiency. This innovative approach addresses the growing demand for secure, user-friendly access control systems, significantly reducing the risk of unauthorized access.
