Abstract

U okviru rada razvijen je višeprotokolni bežični senzorski sustav temeljen na platformi ESP32-C6, čija implementacija predstavlja predložak koji je moguće koristiti u svrhu daljnjeg razvoja IoT sustava različitih namjena. Bežični čvorovi temeljeni su na ESP32 C6 mikrokontroleru te podržavaju mogućnost komunikacije putem ZigBee, Bluetooth i Wi-Fi protokola. Za implementaciju lokalnog servera za prikupljanje podataka i koordiniranje mreže korišten je Raspberry Pi 3B+, na kojem je implementiran podsustav za razmjenu podataka temeljen na MQTT protokolu uz korištenje Mosquitto brokera. Višeplatformska klijentska aplikacija za interakciju korisnika sa sustavom razvijena u programskom okviru Flutter. Razvijeno je pokazno okruženje kroz koje je demonstrirana funkcionalnost svih elemenata rješenja na jednostavnom primjeru korištenja sustava.

Abstract (english)

In this thesis a multi-protocol wireless sensor system based on the ESP32-C6 platform was developed. The system implementation can be used as reusable template for the further development of IoT systems for various purposes. The wireless sensor nodes are based on the ESP32-C6 microcontroller and support communication via ZigBee, Bluetooth and Wi-Fi protocols. A Raspberry Pi 3B+ was used for implementation of a local server for data collection and network coordination, with data exchange subsystem based on the MQTT protocol, implemented using the Mosquitto broker. A cross-platform client application for user interaction with the system was developed using the Flutter framework. An environment for demonstration of the functionality of all elements of the solution for a simple use case was developed.
