MOTUS Stand-Alone Sensor

Turn your buoy into an intelligent data-collecting platform with the Aanderaa MOTUS Wave Stand-Alone Sensor.

There are numerous ways of measuring Ocean Waves. At Aanderaa, we focus on three measurement types: pressure, acoustic, and motion. In this section, we cover the motion-based sensors in the MOTUS family.

MOTUS Directional Wave Sensor is suitable for integration on different buoy types. It is intended for commercial as well as research use. The directional stand-alone Sensor processes wave data and is configurable to directly present parameters and wave spectrum. The sensor can be connected to a SmartGuard using the CANbus-based AiCaP protocol. It can also be connected to a PC or third-party systems through the RS-232 interface.

MOTUS Wave Height Sensor is for wave height only. As the MOTUS Directional Sensor, it is suitable for integration on different buoy types. In the sensor, the directional wave parameters are locked. It is possible to open the wave direction parameters with a software license from Aanderaa later if the need changes.  

MOTUS Lite OEM Sensor is the OEM version of the MOTUS Directional Wave sensor. It is delivered as an electronic board without housing and cables. Please get in touch with the factory for more options and restrictions.

3 features makes the MOTUS Stand-Alone Sensor particularly suitable for integration to different buoys and loggers:

  • For larger buoys, the response to short wavelengths may be suppressed. This can to some extent be compensated for by activating and tuning the build in transfer function.

  • The sensor can be placed in non-ideal location on the buoy. The off-center compensation can be enabled to remove the errors that in some cases may be significant.

  • Buoys may have magnetic parts affecting wave sensors and other sensors requiring a magnetometer or compass. The MOTUS can receive an external compass directly and utilize this to ensure correct wave direction data.
