Interfacing RC522 RFID Sensor with ESP32 Using Arduino IDE

Interfacing RC522 RFID Sensor with ESP32 Using Arduino IDE

In this Article, we learn about how to Interfacing RC522 RFID Sensor with ESP32 Using Arduino IDE.

In the Last post, we learned about how to make ESP32 CAM Face Detection Interface Relay with Buzzer.

Let’s dive into

Components Require:

1. ESP32
2. Single channel Relay module
3. Power supply (12v)
4. RFID (RC522)
5. RFID (CARD)
6. Jumper wires

Circuit Diagram:

How it works:

The RC522 RFID sensor with ESP32 works by using radio frequency identification (RFID) technology to communicate between the RFID tags/cards and the RC522 reader module. The ESP32, acting as a microcontroller, reads the data from the RC522 module and processes it to determine if a specific RFID card is authorized or not.

Usages:

1. Access Control Systems
2. Attendance System
3. Smart Locks
4. Home Automation
5. Identification and Authentication
