Aplicação móvel e Web service para monitoramento e armazenamento dos dados de produção de energia eólica de um pequeno gerador

Abstract

This study presents a mobile application to visualize data generated by a wind turbine located in the building of the Instituto de Redes Inteligentes (INRI) of the Federal University of Santa Maria (UFSM). The application was developed using the Flutter framework in the Dart programming language, making it available for both Android and iOS devices. To receive and store the data, a relational database was implemented using MariaDB and an open-source Raspberry hardware. For the application to be able to communicate with these data, a web service was created and hosted on the same hardware. This web service was developed using the Laravel framework in PHP language, in which several endpoints over the Hypertext Transfer Protocol (HTTP) are implemented, capable of providing specific information about the data generated and saved in the database through files in JavaScript Object Notation (JSON). The use of this application will make the process of monitoring energy generation easier, ensuring that users can visualize the values through graphs and keep a history of the generation, in addition to making the use more accessible, since the application can be accessed at any moment from a mobile phone. It is concluded that the present work enabled the development of data communication and a mobile application, capable of displaying generation data visually and numerically in a friendly interface for end users.
