Implementation of an Internet of Things (IoT) Based Digital Residential Gate Security System
TL;DR
The results indicate that the system performs its main functions according to the specified requirements, and the evaluation was conducted on a limited prototype scale with a limited number of SUS respondents, so the usability results cannot yet be generalized broadly.
Abstract
This study aims to implement an Internet of Things (IoT)-based digital security system for residential gates to improve access management efficiency and real-time monitoring. The system integrates an ESP32 microcontroller, DC gearbox motor, limit switch, Network Time Protocol (NTP), Telegram Bot, Node.js server, MySQL database, and web dashboard to support PIN-based access verification, automatic gate control, real-time status notifications, and digital access activity logging. The main contribution of this study is the practical integration of hardware and software components to support more efficient and manageable residential access security. System testing resulted in 100% functional feasibility and 100% accuracy, while usability testing using the System Usability Scale (SUS) produced an average score of 80, categorized as Grade B (Good). These results indicate that the system performs its main functions according to the specified requirements. However, the evaluation was conducted on a limited prototype scale with a limited number of SUS respondents, so the usability results cannot yet be generalized broadly. The evaluation also did not include quantitative measurements of communication latency and network reliability under short-term and long-term usage scenarios. Future research should involve a larger number of users and evaluate communication latency and network reliability under various operating conditions.
