Aanderaa MOTUS Wave Sensor 5729

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.

MOTUS Wave Buoy Platform Capabilities:

Measure Wave Direction with market leading accuracy

  • Measure accurate wave characteristics with the flexibility of a Met Ocean (ODAS) buoy
  • High sampling rate and mechanical dampening, ensuring low noise
  • Compensate for buoy wave response, off-center placement of sensor and payloads by configurable settings
  • Distinguish direction of swells and wind driven waves 

MOTUS passes the ultimate test while the storm Aina strikes the Norwegian coast
