可以用不同的观点对传感器进行分类：它们的转换原理(传感器工作的基本物理或化学效应)；它们的用途；它们的输出信号类型以及制作它们的材料和工艺等。
根据传感器工作原理，可分为物理传感器和二大类 ：
传感器工作原理的分类物理传感器应用的是物理效应，诸如压电效应，磁致伸缩现象，离化、极化、热电、光电、磁电等效应。被测信号量的微小变化都将转换成电信号。
化学传感器包括那些以化学吸附、电化学反应等现象为因果关系的传感器，被测信号量的微小变化也将转换成电信号。
有些传感器既不能划分到物理类，也不能划分为化学类。大多数传感器是以物理原理为基础运作的。化学传感器技术问题较多，例如可靠性问题，规模生产的可能性，价格问题等，解决了这类难题，化学传感器的应用将会有巨大增长。
