Smart Library Management with QR Code and Raspberry Pi with Pico W

Library management system from ancient age one of the research area and bar codes are extensively used in most of the modern library management system. This Research project is aimed to develop smart library management system using QR code. QR codes are twodimensional matrix barcodes. QR codes can be widely used in both commercial and institutions with the increased use of smart phones, as smart mobile phones can scan the sensible data. Use of QR code in Library management system is very easy but still in primary stage. Library should try to keep up with digital world with various technologies in this modern age. The importance of library system is because these systems are used as primary resource of information by many peoples. Most of the libraries currently working with large number of persons for daily activities and supervision. QR code based Library management system is very efficient and reliable for Librarian, staff and students. This system will simplify library processes to keep track of all records, and make library more directly accessible to its users. In this system. RASPBERRY PI PICO frame work application is being used for College Library database which can be accessed through out the institution. This system works in real time and easy access to information to every member associated with the system. Users must be registered with the system administration after which they can access their accounts and database. It reduces the bourdon on the librarian as it will help to track the books available and issued person for any book and total number of books along with ageing analysis. This research paper presents the design and implementation of a Smart Library Management System leveraging QR code technology and Raspberry Pi Pico W. The system aims to enhance the efficiency and accuracy of library operations, such as book lending, returns, and inventory management. By integrating QR codes with a Raspberry Pi Pico W microcontroller, the proposed solution offers a low-cost, scalable, and user-friendly method for automating library processes. The system utilizes QR code scanning to facilitate quick and error-free transactions, while the Raspberry Pi Pico W serves as the central processing unit, managing data and communication with the library database. The paper details the hardware and software architecture, implementation procedures, and performance evaluation of the system. Results demonstrate significant improvements in transaction speed, accuracy, and overall user experience, highlighting the potential of this technology in modernizing library management systems.
