SmartLib: Automated Library Management with RFID and Mobile Alerts

Library management systems play an important role in maintaining book records, monitoring issue and return activities, and improving user convenience in modern libraries. This project presents Smart Lib Automated Library Management with RFID and Mobile Alerts using RFID technology, automation, and GSM communication for efficient library operations. The proposed system uses an Arduino microcontroller integrated with an RFID reader, IR sensor, GSM module, LCD display, motor driver, and DC motor for automated library management and monitoring. Each RFID card represents a particular book stored in the system database. When a card is scanned, the system displays book details such as issue date, return date, and validity period on the LCD screen. If the return period exceeds the predefined date, a penalty indication is generated along with buzzer alerts for notification. A GSM module is used to send book issue and return details, including due dates, as mobile alert messages to users. An IR sensor is used for person detection, where the motor driver controls a DC motor to simulate automatic door opening and closing operations. In addition, Python programming is used to store library transaction data into Excel sheets for future verification and record maintenance. The proposed system improves library automation, reduces manual management efforts, supports accurate record keeping, and enhances user convenience through RFID-based smart monitoring and mobile alert technologies.
