A Novel Intelligent Door-Lock and Management System Based on STM32 Microcontroller

In rapidly-developing technological world, `Home Security' is getting more and more attention in normal life. The challenge to developing various home security devices is not only ensuring security and safety of users and their home, but also making devices convenience and intelligence. It is important to improve the usability of the intelligent door-lock system as the first entrance of a smart-home. This paper proposes a novel intelligent door-lock system and management system. The design scheme of the system mainly adopts the idea of modular design, dividing the whole system into fingerprint module, RFID module, password module, display module sleep module and communication and client module and other sub-modules.
