Využití Raspberry Pi k monitorování domácnosti

This thesis is dedicated to the introduction of a mini-computer called Raspberry Pi and its practical use for monitoring selected physical variables indicative of air quality in the home. The main objective of this thesis is to create a functional web application that allows the user to monitor physical variables using sensors connected to the Raspberry Pi minicomputer. The theoretical part of the thesis is devoted to a basic introduction of Raspberry Pi minicomputers and a brief historical overview of the development of the Raspberry Pi Foundation. The next stage of the thesis describes alternative products from other companies, including a description of the use of these products for home monitoring. In the last phase of the theoretical part, the SGP30 and BME280 sensors are introduced, which can be used to measure variables such as temperature, humidity, pressure and eCO2 concentration in the air. The practical part of the thesis is devoted to the implementation of a project for monitoring physical variables in the home environment. Firstly, the individual required behaviours and application goals are determined along with the proposed software and hardware. Subsequently, the implementation phase is described, describing how the set requirements and goals were achieved. The implementation phase further describes the individual features including sample codes and presents the achieved results. The last part of the practical section describes the testing process. Finally, the thesis describes the future possible development of the project and briefly describes other possible applications of these minicomputers.
