Nauta: desenvolvimento de um aplicativo móvel e protótipo de módulo embarcado para apoio ao monitoramento de travessias fluviais

Abstract

This article presents the development of NAUTA, an integrated system designed to support the monitoring and management of river ferry crossings, composed of a mobile application, a backend, and an embedded module. The proposal aims to contribute to the modernization of river transportation services by providing features such as ferry location visualization, crossing records, message exchange, operational status monitoring, and telemetry data display. The mobile application is intended for both service users and operators, promoting greater trans parency and organization of crossing-related information. The embedded module prototype was designed considering the future use of the ESP32 microcontroller, due to its low cost, integrated wireless connectivity, and compatibility with sensors used in Internet of Things applications. At this stage, the initial validation was conducted in a controlled environment through a preliminary physical setup and computational simulation of ferry operational variables, such as temperature, fuel level, and battery charge. The results demonstrated the initial feasibility of integrating a mobile application, API, and embedded hardware, providing a basis for future deployments in real operating environments.
