With the deepening of marine engineering, marine early warning systems, and scientific research, the demand for real-time, accurate marine data is rapidly increasing. As a key component of marine monitoring systems, the Ocean Buoy Sensor plays a decisive role in data quality, stability, and long-term durability. Leveraging our deep technological expertise in marine observation equipment, our company deeply integrates high-performance sensing units with self-developed algorithms to provide users with more reliable monitoring solutions.
The Ocean Buoy Sensor is a core sensing device deployed on ocean buoy platforms, used to measure wave, current velocity, attitude changes, and sea surface motion characteristics. Utilizing a nine-axis MEMS-IMU, a high-sensitivity sensor array, and an STM32 microprocessor, it enables continuous, high-resolution data acquisition and supports spectral and directional spectrum calculations with stable attitude tracking capabilities. In practical applications, the sensor can be mounted on wave buoys, drifting buoys, marine monitoring buoys, and marine gliders to form a complete data acquisition system.
Core Features and Advantages
The advantages of the Ocean Buoy Sensor stem from comprehensive improvements in hardware, algorithms, and structural design. First, it boasts a significant advantage in accuracy, effectively reducing integral drift errors and ensuring the reliability of long-term observations. Furthermore, it possesses characteristics such as low power consumption, high strength, and corrosion resistance, making it suitable for marine environments.
Key advantages
High precision and low noise performance: Utilizing a nine-axis IMU combined with a self-developed algorithm, it achieves high-precision measurements of parameters such as wave height, direction, and period.
Low power consumption design: The entire unit's current is less than 50mA, suitable for long-term offshore deployment.
In addition, the Ocean Buoy Sensor's structure employs corrosion-resistant packaging, enabling stable operation under typhoon conditions, strong wave impacts, and prolonged immersion. Its ability to determine wave direction, wave energy, and spectral distribution makes it suitable for multiple scenarios in scientific research and engineering.
The Ocean Buoy Sensor has high versatility in marine environmental monitoring systems, serving various applications such as wave observation, coastline protection monitoring, safety assessment of offshore wind power construction, marine dynamics research, and sea condition monitoring in aquaculture areas.
Our independently developed IMU attitude correction algorithm eliminates error accumulation in solving differential equations and integrating acceleration and velocity, and solves the problem of data instability in the low-frequency range, maintaining high accuracy, especially in the 0.04 Hz low-frequency range, which gives it a significant competitive advantage in the industry. Furthermore, our sensors have been validated in multiple drifting buoys, wave buoys, and glider products, demonstrating strong system compatibility and high reliability, facilitating user deployment.
