RFID based library management system ABSTRACT Wireless sensor networks have the potential to provide unprecedented remote monitoring capabilities that can benefit applications such as industrial control, environmental monitoring, and defense. Radio Frequency Identification (RFID) is one of the most exciting technologies that revolutionize the working practices by increasing efficiencies, and improving profitability. It is often presented as a replacement for today’s barcodes used in library books, but the technology has much greater possibilities, such as individual serial numbers for each item, and the possibility to read these numbers at a distance of several metres. They are simpler to deploy than wired solutions and these networks will enable improved understanding of processes and environments through continual monitoring of a larger set of parameters. In this project the evolution of wireless sensor networks will be presented, using RFID techniques with examples of implementations in library management systems in college. In this project the issue and receving of books are recorded by the use of RFID tags. These cards were based on the DuoProx II, made by HID®, one of the bigger manufactures of proximity security cards. It features both a magnetic strip and an RFID tag, which uses a carrier frequency of 125 Hz and modulates the signal by using Frequency-Shift- Keying (FSK).
