Sistem Lacak GPS Dengan Kontrol Menggunakan Handphone Berbasis IoT

The development of Internet of Things (IoT) technology enables the creation of efficient and remotely accessible tracking systems. This research aims to design and implement an IoT-based GPS tracking system that can be controlled and monitored in real-time using a mobile phone. The system is built using a Neo-6M GPS module for location data acquisition, an ESP32 microcontroller as the main processing unit connected to the internet via Wi-Fi, and a power management system consisting of a lithium battery, a TP4056 charger module, and a step-down module. The hardware design is integrated onto a custom Printed Circuit Board (PCB) and protected by an enclosure designed with CAD software. Test results show the system can acquire coordinate data with high accuracy, even on par with Google Maps, and can maintain the last valid location when the signal is lost. The charger module testing also demonstrated effective performance in fully charging the battery. Overall, this portable tracking system was successfully developed and functions according to its objectives, providing practical ease of location monitoring.
