This project is a fingerprint module based smart lock build over STM32F407. I wanted to make a fingerprint lock system that is has two stage autorization and is easy to use.
Fingerprint recognition technology and traditional password entry method are combined to achieve a high degree of security for user authentication. The system consists of a microcontroller, a fingerprint scanner, an electromagnetic lock, a TFT LCD display, a keypad and a buzzer module. These subsystems interact to implement a series of functions, including accurate fingerprint identification and unlocking. C programming is used for modular programming, which is convenient for debugging, maintenance, and updating. After real-world testing, the system has high recognition speed, fast response speed, and can adapt to various usage conditions.
Project Goal: Create a prototype of an embedded security system that demonstrates biometric integration with microcontroller platforms.
