MICROCONTROLLER-ASSISTED RFID AUTOMATION FOR SMART LIBRARIES

Abstract

Library automation is an essential requirement in modern academic and public institutions to enhance efficiency, security, and user experience. Traditional barcode-based systems are often time-consuming, error-prone, and limited in scalability. Radio Frequency Identification (RFID) technology offers a more efficient and reliable solution for automated identification, tracking, and management of library resources. This paper presents the design and implementation of a microcontroller-assisted RFID-based library automation system using the AT89S52 microcontroller. The system automates processes such as book issuance, return, and inventory management while minimizing human intervention. The experimental results show that the RFID system significantly reduces processing time, prevents book theft, and improves overall operational efficiency compared to conventional methods. The proposed model demonstrates that integrating RFID with microcontroller control units can transform library management into a smart, secure, and scalable system suitable for modern digital libraries.
