Abstract: This invention presents a Hybrid IoT-Based Smart Library Management System that integrates embedded hardware and web-based backend software to automate user access control, library monitoring, and book transaction management within a secured local-network environment. The system employs an ESP32 microcontroller interfaced with RFID readers, a custom-designed low-power servo motor-based electronic locking mechanism, a rechargeable lithium battery backup architecture, and a centralized administrative dashboard. Each authorized user is assigned a passive RFID card with a unique identifier (UID) stored both in the microcontroller memory and the backend database, enabling a hybrid dual-layer authentication that functions independently of continuous network connectivity. During normal operation, RFID-based authentication grants-controlled entry and exit, while user activity records including entry time, exit time, and occupancy duration are synchronized in real time with the backend system. A key innovation is the system's offline operational capability: during power interruption or backend unavailability, the microcontroller continues local UID validation using stored records, and logs all activity events in an internal queue, which are automatically synchronized upon restoration of connectivity and power. The system further incorporates a barcode-assisted book management module enabling users to submit borrowing requests via mobile or web interface, with the backend processing transactions, updating book availability, and generating automated email notifications and return reminders. The proposed low- power locking mechanism consumes electrical energy only during actuation, significantly reducing power demands compared to conventional electromagnetic or solenoid-based systems. By unifying local authentication, offline resilience, low-power access control, and automated resource management, this invention offers a cost-effective and reliable smart library automation solution suited for educational and institutional environments.
