RFID Door Lock System Using ESP32 | How to Make an RFID Door Lock System

In this video, I’ll show you how to build an ESP32-based RFID Door Lock System with a professional IoT web dashboard.
This project records user entry and exit time, automatically calculates total stay duration, and allows manual door lock control through a browser — all in real time.

The system uses an RFID reader, ESP32, active-low relay, I2C LCD, and buzzer, making it suitable for offices, labs, classrooms, hostels, and smart access control applications.
