Present! - IoT Mobile App for Student Attendance and Grades

Present! is an IoT-based student attendance and grade tracking app designed for teachers and students. The app uses React Native Expo for the mobile interface and Firebase for real-time data storage. The app allows students to log their attendance using RFID cards and notifies guardians via SMS when their child checks in or out. The app also supports temporary password changes for students.

Features

• Two User Roles:

  • Students: Can log attendance using their RFID card and change their temporary password set by the teacher.
  • Teachers: Register students by assigning an RFID number and guardian mobile number for SMS notifications.

• RFID Card Scanning:

  • Students use their RFID card to scan their attendance.
  • The device will check the card and the student can toggle to either TIME IN or TIME OUT.

• SMS Notifications:

  • Once attendance is marked, the app sends an SMS to the guardian's mobile number with the student’s name and the time of their check-in or check-out. This ensures parents/guardians are notified in real-time.
  • SIM800L module integrated for SMS functionality.

• Temporary Password Change:

  • Students can change the temporary password provided by the teacher through the app.

• Teacher Registration:

  • Teachers register student details along with the RFID number and guardian mobile number to allow SMS notifications.

Installation

Prerequisites

Make sure the following tools are installed:

• Node.js (for managing JavaScript dependencies)
• React Native CLI (to run and build the mobile app)
• Expo CLI (for building and running the app with Expo)
• Firebase (for real-time data storage)
• ESP8266 (for the hardware side communication)
• SIM800L (for SMS functionality)
• MFRC-522 RC522 RFID Card Reader (for RFID scanning)

Steps

1. Clone the repository:

   git clone https://github.com/DevMike13/StudentSystem.git
   cd StudentSystem

2. Install project dependencies:

   npm install

3. Install Expo CLI (if not already installed):

   npm install -g expo-cli

4. Set up Firebase:

   • Create a Firebase project and configure it in your app.
   • Get the Firebase config and add it to the firebaseConfig.js file in your project.

5. Program the ESP8266:

   • Use Arduino IDE to program the ESP8266 with the SIM800L module for SMS alerts and the MFRC-522 RFID Card Reader for attendance scanning.
   • Install necessary libraries such as ESP8266WiFi and FirebaseESP8266 for Firebase communication.
   • Upload the code to the ESP8266, which will send data to Firebase and trigger SMS notifications via SIM800L when attendance is marked.

6. Run the application:

   npx expo start

7. Open the app in the Expo Go app on your phone, or use an Android/iOS emulator to run the app.

How It Works

1. Student Attendance:

   • The RFID reader scans the student's unique RFID card number.
   • The student presses the button on the app to select TIME IN or TIME OUT.
   • The app then sends the attendance information (including the time) to Firebase and triggers an SMS notification to the guardian’s mobile number via the SIM800L module.

2. Teacher Registration:

   • Teachers can register student accounts by adding their RFID number and guardian's mobile number in the app.
   • The student's temporary password can be set by the teacher in the app, and students can change it as needed.

3. SMS Notification:

   • Upon successful TIME IN or TIME OUT, an SMS is sent to the guardian's mobile number.
   • The SMS contains the student's name and the time of attendance, ensuring the guardian is notified in real-time.

4. Student Account Management:

   • Students can change their temporary password (set by the teacher) through the app for security.

Technologies Used

• React Native: For mobile app development.

  • Expo: To streamline building and testing of the React Native app.

• Firebase: For storing real-time data, including student attendance logs and profiles.

• ESP8266: To communicate with the RFID reader and SIM800L module for attendance scanning and SMS notifications.

• SIM800L: For sending SMS to guardians when attendance is marked.

• MFRC-522 RC522 RFID Reader: To scan student RFID cards for attendance tracking.

• Node.js: To manage backend logic and Firebase integration.
