Microcontroller-Based Door Security System Design Using Fingerprint

Abstract

Technology encompasses all means that fulfill human needs for survival and comfort, and provides specific benefits in various sectors. In this modern era, technology permeates various aspects of everyday life, including security. The objective of this research is to design and implement a door security system based on a microcontroller utilizing fingerprint technology. This system is designed to allow restricted access to a room or area by verifying the user's identity through their fingerprint. The equipment used in this research includes Arduino UNO microcontroller, NodeMCU ESP8266, electromagnetic lock, fingerprint scanner, keypad, relay, door sensor, and Arduino IDE. Prototyping method is employed in the development of this system, with a focus on creating a model or prototype before full implementation. The results of this research indicate that the door security system can recognize registered fingerprints. The evaluation will cover the success of fingerprint recognition and the overall system performance. This research is expected to contribute to the development of biometric-based security technology
