ThingSpeak Platform for IoT Sensor Data Acquisition and Analysis in Shipboard Solar PV Systems

This paper investigates the application of the ThingSpeak platform for real-time monitoring of shipboard photovoltaic (PV) systems. A simulated environment was created using MATLAB to replicate sensor data for key parameters, including temperature, voltage, current, power and solar irradiation. These values reflect operational conditions typical for a ship in the Boka Bay, Montenegro. Data were uploaded to ThingSpeak at regular intervals and visualized through interactive dashboards. The study demonstrates how ThingSpeak, combined with MATLAB, can be a lightweight, cloud-based monitoring solution for maritime energy systems, allowing data to be collected, visualized, and analyzed remotely without the need for sophisticated on-site infrastructure.
