Stm32f1 and stm32subeide programming example - Optical intermittent sensor drive

Light intermittent sensor drive

The light interrupter is （Photo Interrupt Sensor） A transmission type light sensor , The light receiving and transmitting elements are integrated in one package , Please refer to the figure below . Since the method involves shading , It is usually called light interrupter . The output adopts long-life infrared photodiode , The other side is integrated with a single phototransistor and optoelectronics IC For light detection .

Different from mechanical switch , The light interrupter is non-contact （ optics ） switch , By preventing wear （ Contact ） To improve reliability .

This article will show you how to STM32CubeIDE How to use light intermittent sensor in . When blocked , Sensor output low level , When connected , Output high level .

1、 Optical intermittent sensor configuration
