Design and Construction of an IoT-Based Motor Vehicle Security Control and Monitoring System with Google Assistant and GPS

Abstract

The development of Internet of Things (IoT) technology is driving the development of smarter and more integrated motor vehicle security systems. This research designs an IoT-based vehicle control and monitoring system connected to GPS and Google Assistant. The system allows users to track location in real time, control the engine via voice commands, and receive notifications when the vehicle exits a designated zone. Test results show that the response time for Google Assistant and Telegram notifications averages 1–2 seconds, geofencing accuracy reaches ±1–4 meters, and GPS is capable of pinpointing the location based on actual conditions. Furthermore, the vibration sensor proved sensitive, outputting a value of 4095 when detecting vibrations. These findings demonstrate that the system performs reliably in tracking, controlling, and providing alerts, while improving user safety and comfort when accessing the vehicle.
