常用的超声波传感器由压电晶片组成，既可以发射超声波，也可以接收超声波。小功率超声探头多作探测作用。它有许多不同的结构，可分直探头（纵波）、斜探头（横波）、表面波探头（表面波）、兰姆波探头（兰姆波）、双探头（一个探头发射、一个探头接收）等。

超声波传感器是将超声波信号转换成其他能量信号（通常是电信号）的传感器。超声波是振动频率高于20KHz的机械波。它具有频率高、波长短、绕射现象小，特别是方向性好、能够成为射线而定向传播等特点。超声波对液体、固体的穿透本领很大，尤其是在阳光不透明的固体中。超声波碰到杂质或分界面会产生显著反射形成反射成回波，碰到活动物体能产生多普勒效应。超声波传感器广泛应用在工业、国防、生物医学等方面。

传感器能感受规定的被测量件并按照一定的规律转换成可用，信号的器件或装置，通常由敏感元件和转换元件组成。传感器是一种检测装置，能感受到被测量的信息，并能将检测感受到的信息，按一定规律变换成为电信号或其他所需形式的信息输出，以满足信息的传输、处理、存储、显示、记录和控制等要求。它是实现自动检测和自动控制的首要环节。

目前对传感器尚无一个统一的分类方法，但比较常用的有如下三种：

1、按传感器的物理量分类，可分为位移、力、速度、温度、流量、气体成份等传感器

2、按传感器工作原理分类，可分为电阻、电容、电感、电压、霍尔、光电、光栅、热电偶等传感器。

3、按传感器输出信号的性质分类，可分为：输出为开关量（“1”和“0”或“开”和“关”）的开关型传感器；输出为模拟型传感器；输出为脉冲或代码的数字型传感器。

在这里，主要给大家介绍一种在日常生活中运用非常广泛的，给人类社会带来很大便利的传感器——超声波传感器以及其在倒车雷达上的应用。
