Praktická aplikace IoT řešení s využitím open source technologií

This thesis focuses on the Internet of Things. The goal of this thesis was to lay down the theoretical basis necessary for understanding IoT, analyse the pros and cons of open source solutions, compare popular IoT platforms, and design an IoT solution for a specific problem, including its practical implementation. The theoretical basis was gathered based on research and analysis of available sources. The first part of the thesis focuses on this theoretical basis, specifically on the term Internet of Things, individual components that make up IoT devices, various connectivity solutions, security in relation to IoT and also the term open-source. The second part of the thesis demonstrates the process of implementation of a new IoT solution for a household. Addressed problems are an inefficient process of pet feeding and a smartphone overuse stemming from insufficient availability of certain information sources. The practical part of this thesis documents the implementation process, from the initial analysis of said problems, through the design of a solution - a smart mirror and an automatic pet feeder, to a testing phase of the whole solution. The results of this thesis are a clear theoretical basis and working IoT solutions, consisting of two fully operational IoT prototypes, which make up the foundations of a future private IoT ecosystem. The thesis also shows that open source solutions can mean a significant reduction in acquisition costs and an equal or even higher level of security.
