Design and Construction of an Arduino-Based Main Engine Overheating Detection Prototype

Overheating in the ship's main engine, often caused by suboptimal cooling and lubrication systems, poses a high risk to performance and safety. This study aims to design and build an Arduino-based detector prototype. Using a research and development (R&D) method with an experimental approach, the population of b diesel at the Surabaya Maritime Polytechnic, a purposive sample of one Mitsubishi S6B3-MPTA unit. Instruments include Arduino Uno, thermocouple and SW200D sensors, LCD, buzzer, and W
