Marine traffic along the coast needs reliable information on weather, wind and sea state. Such measurements are often obtained using moored buoys with real-time data transmission to users on shore and at sea. The buoys are equipped with various sensors able to measure the parameters needed. The more measurements performed at one buoy the more useful and cost-effective the installation becomes. In general it is challenging to measure waves using a regular measuring buoy. Buoys designed for weather measurements need a certain size and corresponding mooring and the movements in the sea are not particular well suited for measuring waves. Existing wave measuring sensors are rather costly compared to the other sensors used on such buoys. The project aim is to develop a wave sensor measuring wave height and wave direction. The sensor is intended for use with a variety of buoys and will provide reliable wave measurements for marine transport and similar users. By utilizing the latest advances in miniaturized sensors for consumer market coupled with advanced embedded electronics and software, the goal is to develop a new and cost effective sensor for measuring waves on a wide range of measuring buoys.
The Aanderaa MOTUS Wave Sensor 5729 is a directional wave sensor module for use on surface buoys. The MOTUS Wave Sensor is an integrated part of Tideland SB 138P MOTUS Buoy and YSI EMM 2.0 MOTUS Buoy. It is intended for commercial as well as research use.
The sensor processes wave data and is configurable to present parameters and wave spectrum directly.
