Smart temperature and vibration monitoring device for small-scale fishing vessel engines

Monitoring engine condition parameters is crucial for ensuring efficiency and reliability of small-scale fishing vessels. However, existing monitoring device and their application remains limited and they are not extensively utilized for small-scale fishing vessels. This study aims to design and develops a real-time temperature and vibration monitoring device for small-scale fishing vessel propulsion. The proposed device integrates temperature and accelerometer sensors, with ESP32 serving as the main processor. Blynk was used as a real-time monitoring platform. The prototype was tested on a single-cylinder diesel engine by comparing its monitoring results with a standard measurement tool. A trial monitoring the parameters of a single-cylinder diesel engine was conducted for 30 min to assess accuracy by the Mean Absolute Percentage Error (MAPE) value. The results of the trial indicated that the device could effectively record temperature and engine vibration data with a MAPE value below 20%. This level of accuracy indicates the effectiveness of monitoring the performance parameters. The proposed monitoring device can offer notifications regarding the conditions of the small-scale fishing vessel propulsion engines.
