Wave Height Monitoring and Security System on Oscillating Water Column Using ESP32 Microcontroller

This research aims to develop a wave height monitoring and security system for an oscillating water column (OWC) system using the ESP32 microcontroller. The system is capable of collecting real-time wave height data with high accuracy through ultrasonic sensors and is equipped with an automatic security mechanism to ensure the safe operation of the OWC. Testing results show an average sensor error rate of 3% inside the column, 1% outside the column, and an average delay time of 3.3 seconds to open the gate and 1 second to close it. The monitoring device has an error rate below 5%, indicating sufficient accuracy in handling wave fluctuations, and the security mechanism has proven reliable. This research contributes to improved operational sustainability, reduced risk of damage from excessive waves, and optimized renewable energy production from the OWC system.
