Intelligent fingerprint lock based on STM32

In this paper, an intelligent fingerprint lock system based on STM32 is studied. The fingerprint identification technology and the traditional password input method are combined to realize the identification of the user, with high security. The system is composed of MCU control module, fingerprint identification module, electromagnetic lock module, user interaction module and power supply part. These systems cooperate with each other to realize a series of functions such as accurate fingerprint identification and unlocking. In terms of program, C language is used for modular programming, which is convenient for debugging and maintenance and upgrading. After the actual test, the system has high recognition rate, fast response speed, and can adapt to various use environment, and has a broad market prospect.
