Wave Sensor For Buoy

The Wave Sensor for Buoy is a high-precision measurement device designed specifically for marine environments, used to monitor key parameters such as sea surface wave height, period, direction, and energy spectrum in real time. Typically deployed on wave buoys or drifting buoys, it uses a highly sensitive nine-axis MEMS inertial measurement unit to sense the buoy's three-dimensional motion, including acceleration, angular velocity, and attitude changes, in real time, thereby accurately inferring the wave's motion characteristics and energy distribution.

This sensor offers advantages such as compact size, low power consumption, and high reliability, making it ideal for long-term unmanned marine monitoring missions. It utilizes advanced signal processing algorithms and data filtering techniques to effectively eliminate accumulated errors in attitude calculation and integration, ensuring stable and accurate measurement of wave and directional spectra. Its measurement frequency range typically covers 0.04–1.0 Hz, enabling accurate differentiation between wind and swell waves and enabling real-time observation of multi-directional energy distribution.
