Abstract

U okviru rada proučena je arhitektura ESP32 mikrokontrolera te je provedena usporedba porodica ESP WROOM-32 i ESP32-C3. Napravljen je pregled važnijih mogućnosti i protokola koji se koriste u realizaciji IoT sustava. Proučeni su i objašnjeni važni servisi u sklopu AWS IoT cloud platforme: AWS IoT Jobs (OTA), AWS IoT Device Shadow, AWS IoT Fleet Provisioning i AWS IoT Device Defender. Služeći se navedenim AWS servisima, razvijen je pokazni sustav temeljen na ESP32(-C3) mikrokontroleru s funkcijom spajanja na lokalnu pristupnu točku, automatskom registracijom novih senzorskih čvorova na AWS infrastrukturu, mogućnošću udaljene nadogradnje programske potpore odabranih čvorova te pristupom posljednjem poznatom stanju uređaja. Dodatno, izrađena je pokazna web aplikacija s mogućnošću upravljanja IoT uređajima i grafičkom vizualizacijom prikupljenih senzorskih podataka dohvaćenih iz DynamoDB-a, AWS cloud baze podataka.

Abstract (english)

In this thesis the architecture of the ESP32 microcontrollers was presented and the capabilities of ESP WROOM-32 and ESP32-C3 families were compared. An overview of the most important features and protocols used in IoT systems was provided. The most important services within the AWS IoT cloud platform were presented: AWS IoT Jobs (OTA), AWS IoT Device Shadow, AWS IoT Fleet Provisioning, and AWS IoT Device Defender. Using these AWS services, a demonstration system based on ESP32(-C3) microcontroller was developed, with features such as: provisioning a device to a local access point, automatic registration of new sensor nodes on AWS infrastructure, firmware upgrade over-the-air capability for selected nodes, and access to the latest known state of devices. Additionally, a demo web application was developed, with the ability to manage IoT devices and visualize acquired sensor data retrieved from DynamoDB, an AWS cloud database.
