GSM and RFID Based Library Book Availability and Location Finder System

Abstract: GSM & RFID Library book availability & location finder system is very essential for digital libraries. RFID system is now very important because it play a very essential role to reduce human efforts. For find the location of each & every book we need to implement RFID tag. User sends the message to GSM modem. This message is accept by Arduino board & pass it to RFID Reader through level converter. RFID Reader pass that code to RFID Card. RFID Card reads that message & message is transfer to RFID Reader, then Arduino board send that message to Motor driver then Motor starts rotating and if book is available then motor will be stop. Keywords: GSM- Global System for Mobile, RFID- Radio Frequency Identification, Arduino Mega 2560, Arduino software, LCD- Liquid Crystal Display, RS-232-standerd for serial communication.
