The Smart Door Lock system integrates an ESP32 microcontroller, fingerprint sensor, and LCD display to enhance security and convenience. This system allows users to enroll and verify fingerprints, stores data securely on a server, and provides access notifications via a user-friendly interface. Power loss resilience and modular design make it a practical solution for modern access control.
This project presents the design and implementation of a Smart Door Lock system using an ESP32 microcontroller, a fingerprint sensor, a buzzer, and an LCD display. The system enables secure access by enrolling and verifying fingerprints. Data storage is managed via a server connection, ensuring that fingerprint templates remain accessible even after power loss. During operation, the LCD display provides real-time feedback, such as enrollment status and access granted or denied messages, enhancing user interaction. The system is designed to be modular, allowing for additional features such as Wi-Fi, Bluetooth, or UART communication for broader accessibility. Practical applications include residential, office, or industrial access control, where security and convenience are paramount. By focusing on reliability, ease of use, and scalability, this project delivers an innovative approach to smart access control systems.
