1、基于52单片机太阳能自动跟踪系统设计摘要太阳能是已知的最原始的能源，它干净、可再生、丰富，而且分布范围广，具有非常广阔的利用前景。但太阳能利用效率低，这一问题一直影响和阻碍着太阳能技术的普及。太阳能自动跟踪系统的设计为解决这一问题提供了新途径，从而大大提高了太阳能的利用效率。本设计采用光电跟踪的方法，利用步进电机双轴驱动，由光电传感器根据入射光线的强弱变化产生反馈信号到微机处理器。微机处理器运行程序，通过对跟踪机构进行水平、俯仰两个自由度的控制，调整太阳能电池板的角度实现对太阳的跟踪。采用单片机来实现的太阳能追踪系统能有效提高太阳板的光电转化效率，并具有较广泛的应用前景。关键词：太阳能；跟踪
