Design of MCU-based Photoelectric Signal Detection System

As one of the key components for factory automation,photoelectric sensors provide a sensing solution for applications involving fine targets at unfavorable conditions. In this paper a novel scheme of the overall sensor architecture is developed according to photoelectric sensing technology. Due to require- ments of fast response and strong anti-interference performance, a photoelectric sensor signal detection al- gorithm based on C8051 F330 MCU is proposed to sense the existence of the target. Experimental results show that the simple detection system can render accurate detection along with apparently improved relia- bility, which could be widely implemented for detection of fine objects with photoelectric sensor.
