In its theoretical part, the diploma thesis aims to analyze the current state and technological possibilities of the Internet of Things in modern society. It defines the Internet of Things, sets the general framework, goals for civilization and technological possibilities. It describes the possibilities and trends in various areas of application that this relatively new phenomenon in the sphere of communication and information technologies provides. It also addresses potential risks, security, and economics issues. In the practical part of the diploma thesis solves the problem of indication of open windows and notification of the user about the change of status both in the place and anywhere in the world using the Internet. The aim is to design, develop, program and practical implementation of solutions that lead to solving the problem of using the Internet of Things. The method is incremental development based on design, ending with testing and practical deployment of the finished device. New pieces of knowledge and findings are continuously recorded so that they can be re-used in the development of the project or other projects. The diploma thesis is written in style to familiarize the reader with the phenomenon of the Internet of Things, its technological possibilities and to educate used tools for the implementation of a functional device on a practical demonstration. By replicating the project management procedures used in the design, development and practical solution, successful implementation of simple to medium-complex solutions can be achieved. The use of newly acquired experience described as lessons learned at the end of the work will help avoid mistakes in the introduction of Internet of Things projects.
