Abstract

The paper presents the development of a functional prototype of a GPS location tracking system
with data display on an interactive map. The theoretical part of the paper analyzes Arduino boards,
the ESP32, and the Raspberry Pi Zero 2 W as potential platforms for system implementation, while
the ESP32 microcontroller was selected for the practical realization of the prototype. The system is
based on connecting a NEO-7M GPS module to an ESP32 microcontroller, which collects geographic
coordinates, processes them and sends them to a remote server via an internet connection. HTTP
communication is used for data transfer, with coordinates sent in JSON format. The server part of
the system was created using the Flask web framework, while the Leaflet library with OpenStreetMap
cartographic support was used for location visualization. On the web interface, the current position
of the device is displayed using a clearly visible marker on the map, which provides the user with a
simple and clear insight into the location of the monitored object. The prototype was tested in an
open area, with GPS data sent to the server every 10 seconds. During testing, the system worked
stably and no transmission delays or communication difficulties were recorded. The presented system
confirms that using available hardware and software tools it is possible to create a simple, adaptable
and functional IoT solution for remote location monitoring in real time. The system is suitable for
educational purposes, prototype development and as a basis for further upgrades, such as saving
movement history, displaying routes or monitoring multiple devices simultaneously.
