论文利用光学滤波片及光敏元件比较式原理设计了一种太阳光自动跟踪装置,通过滤波片将太阳光波段中光敏电阻最敏感的光强投射到四个光敏电阻上,在单片机中对采集的信号比较输出来控制舵机转动,使太阳光接收模块转向光照最强的方向,接收到最强的光强。
In this paper, an automatic solar tracking device is designed based on the comparison principle of optical filter and photosensitive element. The most sensitive light intensity of the photoresistor in the solar band is projected onto the four photosensitive resistors through the filter. Signal comparison output to control the servo rotation, so that the sun light receiving module to the strongest light direction, receiving the strongest light intensity.
