The dependence of coastal areas on fossil fuels and intermittent renewable energy sources remains a significant obstacle to the electrification of remote regions. This research introduces LEVIATHAN-X, a hybrid energy generation system that integrates ocean wave and solar energy with a hydraulic pressure stabilization system. The primary innovation lies in utilizing the MA 40 Hydraulic Piston to convert mechanical wave energy into fluid pressure stored within a hydraulic accumulator. This design is specifically engineered to mitigate the energy output fluctuations common in conventional mechanical transmission systems. To ensure system reliability, an Internet of Things (IoT)-based monitoring system was developed using an ESP32 microcontroller, integrating a 0–1.2 MPa Pressure Transmitter, an INA219 sensor for DC power measurement, and a KY-003 Hall Effect sensor to track the piston’s mechanical cycles. Furthermore, a custom software solution implements an Auto-Zeroing function to eliminate the sensor's 0.5V voltage offset, significantly enhancing reading accuracy under static conditions. Test results demonstrate that LEVIATHAN-X generates stable operating pressures between 3.61 Bar and 4.79 Bar. The IoT system successfully achieved real-time data transmission with accurate mechanical detection ("DETECTED" status) and a stable system voltage of 1.00 V. By dampening pressure fluctuations through a hydraulic accumulator, LEVIATHAN-X provides a robust, efficient, and scalable platform for hybrid power generation in coastal areas.
