摘　　要：在此阐述了利用光敏电阻寻找直射太阳的原理,以STC12C5A60S2为控制核心,设计了一种自动太阳能跟踪器。太阳照射情况通过太阳能电池板4边上的4个光敏电阻测得,经过放大后输送到单片机,在单片机内由软件进行分析计算,得出电池板需要偏移的方向和角度,最后通过2个伺服电机对电池板左右和上下偏移进行控制,从而提高了转化效率。The principle to look for the direct sun by using photosensitive resistance is expounded in this article. An automatic solar tracker taking the STC12C5A60S2 as its core was designed. The sun’s irradiation status is measured by the four photosensitive resistances embedded on four sides of the solar panel,sent to the single chip microcomputer（SCM）after amplification,and then analyzed and calculated in the SCM by software to get deviation direction and angle that the panel needs to be moved. At last,two servo motors are adopted to control panels’leftright and updown migration,and improve the luminous efficiency.
