The aim of this article is to show how the Bares sensor works. This sensor
has a microcontroller, an accelerometer, a gyroscope, a magnetometer and a communication
board. It is designed to measure the displacements of the marine free
surface for finally obtain the ocean parameters that describe the state of the sea.
Currently these sensors are very expensive and it is necessary to reduce the costs. We
made the Bares sensor with modern low costs components but with good features.
