光电传感器的应用

The Application of Photoelectric Sensors

光电传感器是把被测量的变化转换成光信号的变化,然后,借助光电元件把光信号转换成电信号来实现控制。如光电开关、光感电阻、光感二极管、光电池、光纤等。

Photoelectric sensor transforms the measured changes to optical signal changes,and control is realized with photoelectric devices such as photoelectric switches,light sensation resister,light diodes,photovoltaic cells,optical fiber,which transform optical signals to electrical signals.
