MOTUS Wave Sensor 5729 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. 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 RS232 interface. Key features • User configurable transferfunction to compensate for buoy frequency response • Configurable compensation algorithm for installation outside of buoy center. • Built-in solid state 9-axis accelerometer/gyro/ magnetometer. • Options for external compass ensuring high directional accuracy even if the wave sensor is installed close to magnetic components. • A compact field friendly low power multi-parameter wave sensor. • Wide range of parameters are calculated inside the sensor, configurable output. • Direct readout of engineering data • Integration time from 5 to 60 minutes. • RS-232 output for integration to most third party Dataloggers. • Customer configurable separation frequency between wind and swell waves • Extremely rugged and watertight. Handles 30 meter knockdown • Low power consumption, <110mW @12V Applications • Oceanographic research • Marine Transport • Offshore / Oil & Gas • Aquaculture / fisheries • Environmental management • Infrastructure design / Survey companies • Offshore wind Internal or External Compass The sensor is using an internal compass in order to reference directional data to geographical or magnetic north. If the magnetic field is disturbed by the buoy structure or payload an optional external compass may be used. This compass may either be connected via the AiCaP bus or using RS-232 input. At RS-232 input the sensor accepts heading given in NMEA 0183 format. Sensor communication protocols The AADI Real-time collector PC software can be used for communication with the sensor. It simplifies the sensor configuration process and saves sensor data to files on a PC. The AADI Real-Time communication protocol is a XML-based protocol which also includes numerous metadata provides the Smart Sensor Terminal protocol a simpler protocol that can be used in most third party systems. The size of the output message can be reduced in both protocols by only enabling the necessary data parameters. Both protocols use ASCII output which makes it directly readable without any conversion (no binary data). Sensor as a part of a system The MOTUS sensor is designed to be a part of the Aanderaa hydrography/meteorology buoy (ODAS) solution with easy expansion with a large number of additional sensors e.g. single point currents, current profiler, various water quality and meteorological sensors. Mooring consideration In order for the wave sensor to fully capture the required movements of the buoy a more flexible mooring is required. To obtain the required flexibility one section of the mooring should consist of a rubber cord. Guidelines for mooring design are available or the mooring may be ordered as a part of the b
