Keyless Entry: Fast scanning and validation of registered RFID cards. Web Dashboard: Add/remove users and manually lock/unlock the door via browser. Activity Tracking: Logs entry/exit times and calculates total stay duration. Operating Range & System Thresholds Key Features Keyless RFID Authentication: Gain instant access using unique RFID cards or tags via the fast and reliable MFRC522 reader. If the card isn’t registered, the door stays locked. Built-in Web Dashboard: No need for physical key management or hardcoding. Connect to the system via Wi-Fi and use your web browser to easily add or delete users, check lock status, and manually control the door. Real-Time Activity Logging: Keep track of who comes and goes. The system records the user’s name, entry time, exit time, and total stay duration, making it perfect for both security and attendance tracking. Persistent Offline Storage (SPIFFS): All user data and access logs are safely stored locally in JSON format on the ESP32’s flash memory. Your data remains secure and accessible even after a power outage or restart. Active Monitoring & Alerts: A crisp 16×2 I2C LCD screen displays real-time status updates (e.g., “Welcome,” “Access Denied”), while an integrated buzzer provides instant auditory alerts for unauthorized scan attempts. Automated Relay Control: Features a robust relay mechanism that safely triggers your electronic door lock upon successful authentication and automatically secures it when the user exits.
