Abstract

Ovaj rad predstavlja implementaciju jednostavnog IoT sustava koji koristi razvojnu ploču s mikrokontrolerom i ultrazvučni senzor za mjerenje udaljenosti. Primarni cilj je uspostaviti pouzdanu komunikaciju između mikrokontrolera i IoT platforme. Oprema korištena u sustavu uključuje razvojnu ploču ESP32 i ultrazvučni senzor HC-SR04. Programiranje se vrši u Arduino okruženju. Mikrokontroler očitava udaljenost sa senzora i prenosi telemetrijske podatke na IoT platformu za praćenje u stvarnom vremenu. Dvije poznate IoT platforme na koje se mikrokontroler zasebno povezuje su Azure IoT Central i ThingsBoard, koje omogućuju analizu i grafički prikaz telemetrijskih podataka. Dani su kriteriji odabira samih platformi i njihova usporedba. Dodatno provodi se testiranje pouzdanosti cijelog sustava na odabranim mjerenjima i usporedbom preciznosti očitanja senzora prema stvarnim udaljenostima. Rezultati pružaju uvid u pouzdanost sustava za primjene Interneta stvari.

Abstract (english)

This thesis presents the implementation of a simple IoT system that uses a development board with a microcontroller and an ultrasonic senzor for distance measurement. The primary goal is to establish reliable communication between the microcontroller and the IoT platform. The equipment used in the system includes the ESP32 development board and the HC-SR04 ultrasonic sensor. Programming is done in the Arduino environment. The microcontroller reads the distance from the sensor and transmits the telemetry data to the IoT platform for real-time monitoring. Two well-known IoT platforms to which the microcontroller connects separately are Azure IoT Central and ThingsBoard, which enable the analysis and graphical display of telemetry data. This thesis presents the criteria for selecting platforms and their comparison. Furthermore, the reliability testing of the entire system is carried out on selected measurements. The results provide insight into system reliability for Internet of Things.
