Application Scenarios

Frankstar Wave Sensor 2.0 is widely deployed in coastal monitoring buoys, offshore weather buoys, drifting buoy networks and unmanned marine platforms. Typical application fields cover coastal environmental monitoring, maritime safety early warning, offshore engineering surveys, university oceanographic research and ocean climate observation.

Ocean waves are constantly changing under the influence of wind, currents, tides, atmospheric conditions, and seabed characteristics. Understanding these changes is essential for oceanographic research, coastal monitoring, marine engineering, offshore operations, and environmental observation.

A reliable Wave Sensor provides the data needed to understand wave conditions, including important parameters such as wave height and wave period.

From research buoys and coastal observation stations to integrated ocean monitoring systems, wave sensors can provide continuous measurements that help researchers and marine professionals better understand the dynamic marine environment.

FrankStar develops wave monitoring equipment designed for practical marine observation, with a focus on compact installation, low power consumption, and efficient field deployment.

What Is a Wave Sensor?

A wave sensor is an instrument used to measure the movement and characteristics of surface waves.

Depending on the measurement technology, wave sensors can observe parameters such as:

Significant wave height
Wave period
Maximum wave height
Mean wave characteristics
Wave direction
Wave frequency or spectrum

Wave measurements can be collected from different platforms, including:

Oceanographic buoys
Fixed marine monitoring stations
Coastal observation platforms
Research vessels
Offshore structures
Integrated ocean monitoring systems

The collected data can then be used for oceanographic analysis, marine engineering, environmental assessment, and operational decision-making.

Why Is Wave Monitoring Important?

Wave conditions can change significantly over relatively short periods.

A sudden increase in wave height can affect vessel operations, coastal structures, offshore equipment, and marine survey activities. Long-term wave observations can also help researchers understand seasonal and regional ocean conditions.

Wave monitoring is therefore important for several areas.

Oceanographic Research

Wave observations help researchers study the interaction between wind, waves, currents, and other oceanographic processes.

Coastal Engineering

Reliable wave data is essential when designing and evaluating coastal structures such as:

Breakwaters
Seawalls
Jetties
Harbors
Offshore structures
Marine Operations

Wave conditions can influence the safety and efficiency of:

Vessel operations
Marine construction
Offshore maintenance
Oceanographic surveys
Aquaculture activities
Environmental Monitoring

Long-term wave observations can contribute to studies of coastal erosion, sediment transport, shoreline changes, and marine environmental dynamics.

What Parameters Can a Wave Sensor Measure?

A wave monitoring system may measure several different characteristics of the sea surface.

Wave Height

Wave height is one of the most important parameters in wave observation.

It describes the vertical difference between the crest and trough of a wave.

For marine monitoring applications, wave height information can be used to evaluate sea-state conditions and identify changes in wave energy.

Significant Wave Height

Significant wave height (Hs) is commonly used to describe the overall condition of a wave field.

It provides a statistical representation of the larger waves within an observed wave record and is widely used in oceanography and marine engineering.

Wave Period

Wave period describes the time interval between successive waves passing a reference point.

Wave period provides additional information about the characteristics and energy distribution of the observed wave field.

Combining wave height and wave period gives a more useful description of sea conditions than either parameter alone.

Wave Direction

For applications requiring directional wave information, a suitable wave monitoring system may also determine the direction from which waves approach.

Directional information can support:

Coastal engineering
Wave modeling
Sediment transport studies
Offshore engineering
Oceanographic research
How Does a Wave Sensor Work?

Different wave sensors use different measurement principles.

Depending on the instrument design, wave measurements may be obtained by detecting changes in:

Water surface elevation
Underwater pressure
Water particle motion
Acoustic signals
Motion of a floating platform

The measurement system collects a continuous time series and processes the data to determine wave characteristics.

A typical wave monitoring process can be summarized as:

Wave Motion → Sensor Measurement → Data Acquisition → Signal Processing → Wave Parameters

The processed data can then be stored locally or transmitted to a monitoring platform depending on the system configuration.

FrankStar Wave Sensor 2.0

FrankStar’s Wave Sensor 2.0 is designed for applications where compact size, low power consumption, and convenient deployment are important.

The sensor incorporates several features intended to simplify marine wave observation.

Ultra-Low Power Consumption

The Wave Sensor 2.0 has a power consumption of approximately 0.08 W.

Low power consumption is particularly valuable for autonomous marine monitoring systems where the available energy budget is limited.

This makes the sensor suitable for integration with:

Oceanographic buoys
Solar-powered monitoring platforms
Autonomous observation systems
Remote marine stations
Compact and Easy to Install

The compact design helps simplify installation and integration.

For field teams working with marine observation equipment, reducing installation time can make deployment and maintenance more efficient.

The Wave Sensor 2.0 is designed for approximately 5-minute installation, helping users quickly configure the sensor for field observation.

High-Temperature Resistance

The sensor is designed to operate in demanding environmental conditions, including marine environments where equipment may be exposed to elevated temperatures.

This makes environmental adaptability an important consideration for long-term deployments.

One-Port Design

The one-port configuration helps simplify system integration and installation.

It can be particularly useful when integrating the wave sensor into compact monitoring platforms where space and connection interfaces need to be carefully managed.

Applications of Wave Sensors
Oceanographic Buoys

Wave sensors are commonly integrated into oceanographic buoys to provide continuous information about surface wave conditions.

A buoy may combine wave measurement with:

Meteorological sensors
CTD sensors
Water-quality sensors
ADCPs
GNSS positioning
Satellite communication

This creates a multi-parameter ocean observation platform.

Coastal Monitoring

Wave sensors can be installed at coastal monitoring locations to observe changes in local wave conditions.

Long-term observations can support research into:

Coastal erosion
Sediment transport
Shoreline changes
Wave climate
Coastal hazards
Offshore Engineering

Wave conditions are important when designing and operating offshore structures.

Wave data can support engineering studies for:

Offshore platforms
Marine renewable energy systems
Subsea infrastructure
Offshore construction
Marine equipment deployment
Port and Harbor Monitoring

Wave conditions inside and around ports can affect navigation, vessel berthing, and port operations.

Wave sensors can provide site-specific data to support harbor planning and operational monitoring.

Marine Research

Research institutions can use wave sensors to collect field data for oceanographic studies, numerical model validation, and long-term observation programs.

Wave Sensor Integration with Other Marine Instruments

Wave data becomes even more valuable when combined with other oceanographic measurements.

For example:

Wave Sensor + CTD + ADCP

can provide information about:

Surface waves
Temperature
Salinity
Water depth
Current velocity

An integrated buoy can further combine:

Wave Sensor + Meteorological Sensor + Water-Quality Sensors + GNSS + Satellite Communication

This allows a single platform to collect multiple types of marine environmental data.

Such integrated observation systems are increasingly important for long-term and autonomous ocean monitoring.

Wave Sensor vs. Wave Monitoring Buoy

A wave sensor and a wave monitoring buoy are related but different components.

A wave sensor is the measurement device responsible for collecting wave-related data.

A wave monitoring buoy is the complete observation platform that may include the wave sensor together with power supply, data acquisition, communication, positioning, and other sensors.

In other words:

Wave Sensor = Measurement Component

Wave Monitoring Buoy = Complete Observation Platform

This distinction is important when designing an ocean monitoring system because the sensor needs to be compatible with the selected buoy, data acquisition system, power supply, and communication architecture.

What Should You Consider When Choosing a Wave Sensor?

Several factors should be considered before selecting a wave monitoring sensor.

Measurement Parameters

Determine whether the project requires wave height, wave period, wave direction, wave spectrum, or multiple wave parameters.

Power Consumption

For autonomous buoys and remote stations, low power consumption can significantly influence system operating time.

Installation

Consider the installation method, mounting structure, connection interface, and expected deployment time.

Environmental Conditions

The sensor should be appropriate for the expected temperature, salinity, wave conditions, and duration of underwater or marine exposure.

Data Interface

The sensor should be compatible with the data acquisition system used by the monitoring platform.

System Integration

If the project requires multi-parameter monitoring, the wave sensor should be capable of integration with other instruments such as CTDs, ADCPs, meteorological sensors, and water-quality sensors.
