RFID based Identity Management System - IoT implementation

This is a project done as part of a course titled IoT & Cyber Physical Systems, Department of ECE, NIT Warangal

Project Outline

Hardware components used	Software components used
ESP32 development board	Arduino IDE
RFID RC522 reader module	XAMPP server
SSD1306 OLED 128X64 display module	PHP source code
Male-to-male jumper wire X 11	RFID RC522 library
Solderless breadboard mini X 2	ESP32 library and board manager
	Adafruit SSD1306 library

Technologies Used

• Embedded C
• PHP
• MySQL
• Apache 2 server (XAMPP)
• Javascript
• CSS

Network Topology

Interfacing of the components

ESP32 to RC522 PIN layout	ESP32 to SSD1306 Display PIN layout
D2 -> SDA	GND -> GND
D18 -> SCK	VIN -> VCC
D23 -> MOSI	D22 -> SCL
D19 -> MISO	D21 -> SDA
GND -> GND
D5 -> RST
3V3 -> 3.3V

Steps to implement

1. Deploy MySQL and Apache server from the XAMPP control panel
2. Configure localhost of the server with the MySQL database. After creating the database, go to http://localhost/nitw-ims/ ¹
3. Set up ArduinoIDE for the ESP32 development board
4. Connect the ESP32 board via USB and upload the source code sketch source/source.ino
5. Admin account and user accounts are to be updated on the database hosted on the local server. Default credentials: email: admin@gmail.com, password: 123
6. Do test runs with different RFID cards/tags
