Student college alert system to parents by their entry at the college premises by using RFID and GSM sms technology


Abstract
Auto-ID technologies have been used to reduce the time and man power to input data manually. There are still some auto-ID technologies require someone to manually scan the tag to capture the data such as in bar coding technology. In contrast, Radio Technology Identification (RFID) is a technology which does not require anyone to do any manual scanning, but it uses radio waves to detect man, animals, data, or any other materials plugged with RFID tag automatically. The RFID tag combines a type of microchip and an antenna, to detect the subjects and transmit the data. The subjects are detected by the microchip and the information is transmitted by an antenna. The advantage that RFID can detect subjects from a range makes it highly usable for data storage or data extraction.

The main aim of this project is to provide information to the parents, that their children have reached the school safely, through RFID technology. Each student will be equipped with RFID tag along with the school ID card. The school bus picks up the students from their respective defined bus stops and drops in the school. When the student gets down the bus and tries to enter into the school through the main gate, the RFID reader, fixed to the gate, reads the data from the RFID tag of the student. This information will be passed to the main controlling unit. Thus, the microcontroller reads the input data from the reader and sends a predefined message using GSM to the predefined number along with the time. RTC is used to read the time.
