Fingerprint Door Lock System Using Arduino

Abstract

This thesis presents the design and implementation of a fingerprint door lock system using Arduino Uno microcontroller. The system uses a fingerprint sensor module to authenticate users and control an electronic door lock for secure access. The hardware components used in this system include Arduino Uno, fingerprint sensor module, a relay module, solenoid door lock and an adapter. The software components include a program for interfacing the fingerprint sensor with Arduino. The system was tested for functionality, security, and usability. The result shows that the system is capable of accurately identifying authorized users and granting them access while preventing unauthorized access.
