| Abstract: | Wave height sensor is real - time equipment of wave height acquisition in the wave simulation experiment. We develop a new type of wave height sensor, which includes structure design and counting process of sensing element, detailed schematic of detection circuit and program flow of SCM （single -chip microcomputer）. The principle of wave height sensor is based on the difference of relative permittivity of water and air, which is response to changes in wave height. According to the practical test, the system is stable, expeditious and accurate highly. |
