ESP32 Fingerprint Door Lock System | DIY Smart Lock Project

In this video, I’ll show you how I built a Fingerprint Door Lock System using the ESP32 microcontroller. This smart lock offers secure access control by scanning fingerprints and unlocking the door without the need for keys or PINs.

We’ll cover everything from the hardware connections, fingerprint sensor integration, and code uploading to the final working demo. Whether you're a beginner or an IoT enthusiast, this project is a great step toward building your own home automation system!

What You’ll Learn:

Interfacing a fingerprint sensor with ESP32

Using the Adafruit Fingerprint Sensor library

Controlling a door lock mechanism (relay/solenoid)

Enrolling and matching fingerprints

Creating a secure and functional smart door lock


Components Used:

ESP32 Dev Board

Fingerprint Sensor (R305/GT521F52/etc.)

Relay Module / Solenoid Lock

Power Supply

Jumper wires, breadboard
