摘　　要：波高传感器用于在波浪模拟实验中实时采集波浪高度.通过对比各类液位传感器结构和电容量的检测方法,并结合分析、计算和单片机技术,研发出一种响应速度快、测量精度高的波高传感器.其测量的基本原理是根据水和空气的相对介电常数不同,以响应波高的变化.研究内容包括传感器敏感元件结构设计和公式推导、传感器检测电路原理和SCM(单片机)程序流程.经实际测试,该传感器测量精度高、工作稳定、响应迅速.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.
