In this project, we will interface the R305 Fingerprint Sensor with ESP32 Module to design a Smart Door Lock Security System.

Security is a major concern in our day to day life, and digital locks have become an important part of these security systems. Fingerprint sensor-based is one of the safest door locking system as it has the ability to identify and distinguish every person individually without making any error. The fingerprint-based security system can be used in many places like Industries, Offices, and Colleges or even at our home.

This project is a fine combination of “Biometrics technology” and “Embedded system technology”. We have seen a Password-based security system and RFID based security system, which is insecure and anyone can have access. The main feature or specialty of the fingerprint is that it is unique. It gives a high level of security than other security systems.

So in this project, we will learn how to make ESP32 Fingerprint Sensor Based Door Lock Security System. We will simply interface the R305 Fingerprint Sensor Module with ESP32 Development Board. We will use a Solenoid valve to lock/unlock the door. The 0.96″ SSD1306 OLED Display will display the status of matched/unmatched finger and door locking and unlocking status. The PCB board Gerber file and Source Code/Program written in Arduino IDE is shared below.
