Project description

Overview all_door_access_system is a full-stack IoT access-control platform built around an STM32F103C8T6 door controller. The embedded system supports password, AS608 fingerprint, MFRC522 RFID, and remote door-opening methods while controlling a physical relay for the lock. The system connects the embedded controller to a Mosquitto MQTT broker and a FastAPI backend. MySQL stores users, devices, and access logs, Redis handles caching, authentication state, and device status, and WebSocket connections provide real-time updates to the management interface. Web, mobile, and WeChat Mini Program…
