Multiband solar sensors data acquisition and cloud processing
Hertl, Vít ; Kaczmarczyk, Václav (oponent) ; Holek, Radovan (vedoucí práce)
This master's thesis builds upon the foundations laid in the same-titled semestral thesis. At the beginning the fundamental properties of sunlight that are needed for understanding of the performance ratio computation are briefly mentioned. After that the solar sensors developed in ReRa Solutions which provided the solar irradiance measured data are described. In the following literary research part the alternatives to unreliable sensor's Wi-Fi connection are compared and the most suitable connection technology is concluded to be LoRa. In the practical part the design and development process of a single page application solution is described in detail. The application allows the sensors to log measured data into the database and is able to retrieve and display them back to the user in an intelligible form. The application benefits from modern programming languages and frameworks (e.g. Kotlin, Spring, TypeScript, React, Material-UI). The database model was designed with respect to real-world scenario introducing the monitored area concept allowing extensive configuration possibilities. Then the model was transferred into the database in the form of programmable entities. Further, the client-server communication via REST API allowing role-based authentication was implemented. The application GUI allows to configure the environment according to user needs and renders interactive graphs with sensor measured data. The application was deployed in Google Cloud with a separate database.
