Introduction
A Student and Employee Attendance System using GPRS Communication is an embedded solution that automates attendance monitoring and transfers attendance records to a remote web server through HTTP and TCP/IP protocols. The system minimizes manual work, improves record accuracy, and allows administrators to monitor attendance from any location using an internet connection. It is suitable for educational institutions, offices, industries, and training centers where real-time attendance management is essential.
System Overview
The attendance system consists of a microcontroller, identification module (RFID, keypad, or biometric), GSM/GPRS modem, LCD display, and web server. When a student or employee marks attendance, the controller verifies the identity and sends the attendance information to the server through GPRS using TCP/IP and HTTP communication. The information is stored in a centralized database for future reference.
Working Principle
- The user authenticates using an RFID card, fingerprint, or unique ID.
- The microcontroller verifies the authentication details.
- Date and time are collected from the Real-Time Clock (RTC).
- Attendance information is displayed on the LCD.
- The GSM/GPRS module establishes an internet connection.
- Attendance data is transmitted to the web server using HTTP over TCP/IP.
- The server updates the attendance database instantly.
- Administrators can access reports through a web application.
