Design and Development of Biometric and Keypad Based Smart Door Security System for Residential Building

Abstract

A door access system's development involves many characteristics, from the most basic a keypad to the most sophisticated using smart cards and biometrics. The Arduino-Based Door Access System was created to address the problems of maintaining and upgrading the current system. This study covers using an Arduino microcontroller in a door entry system. One kind of microcontroller that has its programming language is  Arduino. It may be used for experiments because it contains an electrical prototyping platform of its own. The keypad and fingerprint scanner are the two inputs for this project. The outputs consist of an LCD display, a siren, an indicator, and a magnetic switch. Based on the accuracy results of testing five people, each with four distinct fingerprints, connecting all inputs and outputs with Arduino led to accurate results in opening the door. The result that appears on the LCD display is the output, and the inputs are the password that is entered via the keypad and the details that are retrieved by scanning a fingerprint. This project is trustworthy because it uses an Arduino Microcontroller and a straightforward technique to raise the security level of the door access mechanism.
