This document describes an embedded system that uses RFID and GSM to send SMS alerts to parents when their child attends college. The system uses an AT89S52 microcontroller interfaced with a GSM modem, LCD display, RFID reader, and other hardware. It is designed to issue each student an RFID tag. When a student enters college and scans their tag, the system sends a message to the student's parents to notify them of the attendance. The system is intended to keep parents informed about whether their children are attending classes regularly.

STUDENT COLLEGE ALERT SYSTEM TO PARENTS BY THEIR ENTRY AT THE COLLEGE PREMISES
BY USING RFID & GSM SMS
ABSTRACT
AIM:
THE MAIN OBJECTIVE OF THIS PROJECT IS TO DEVELOP AN EMBEDDED
SYSTEM, WHICH IS USED TO SEND A MESSAGE AFTER HIS SON/DAUGHTER
ATTENDED FOR THE COLLEGE FOR TAT PARTICULAR DAY.
IMPLEMENTATION:
THIS PROJECT IS IMPLEMENTED 8051 BASED AT89S52 DEVELOPED BOARD
INTERFACED WITH GSM MODEM AND LCD FOR DISPLAYING THE DATA.

NOW A DAY’S STUDENTS ARE NOT MUCH INTERESTED TO GO TO
COLLEGES. TO LOOK AFTER SUCH PERSONS OUR EMBEDDED PROJECT IS VERY
MUCH USEFUL. AT ACCORDING TO THIS PROJECT WE WILL ISSUE AN I-BUTTON
TO EACH AND EVERY STUDENT IN THE COLLEGE. IN OUR PREMISES WE WILL
KEEP A READER FOR THAT I-BUTTON. THAT READER I ATTACHED WITH A
MICROCONTROLLER BASED BOARD ALONG WITH GSM MODEM. WHILE STUDENT
ENTERS INTO COLLEGE HE HAS TO KEEP HIS I-BUTTON AT THE READER. BY
KEEPING HIS I-BUTTON AT THE READER AN INTERRUPT WILL BE GENERATED
AND USING THAT INTERRUPT A MESSAGE WILL BE SENT TO HIS/HER PARENT
AUTOMATICALLY.
THE SYSTEM USES A COMPACT CIRCUITRY BUILT AROUND FLASH
VERSION OF AT89S52 MICROCONTROLLER. PROGRAMS ARE DEVELOPED IN
EMBEDDED C. ISP IS USED TO DUMP THE CODE INTO THE MICROCONTROLLER.
SOFTWARE:
EMBEDDED ‘C’
RIDE TO WRITE CODE
ISP TO BURN THE CHIP
