1. 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).
