The µ-Wave-II Inertial Wave Height Sensor is a +5v to 30v, low powered (150mW@12v) wave system that reports heading, significant wave height, dominant wave period, dominant wave direction, maximum wave height and maximum period via RS-232. Also available by user selection is: pitch and roll, the first 5 Fourier coefficients and accelerations. The µ-Wave-II is powered by the SeaView Systems SVS-603 9DOF Inertial Wave sensor and is available from OSIL as part of an integrated buoy system. µ-Wave-II represents a new generation in accuracy and capability for buoy based wave sensing. µ-Wave-II can turn any existing buoy into a wave measurement buoy.
