基于光敏电阻的太阳能板光源自动跟踪演示装置

Automatic tracking demonstrator of light source using solar panel and photoresistor

从大学物理传感器类实验出发,以光敏电阻的应用为例,设计研究光敏电阻在亮光和暗光下的特性实验,利用光敏电阻模拟控制路灯“晚上亮灯、白天不亮”的效果,并制作了太阳能板光源自动跟踪演示装置.在太阳能板4个方位对称地安装光敏电阻,并置于二维转动云台上,实现在手动模式下,通过按键调节太阳能板转动;在自动模式且弱光环境下,自动跟踪手机点光源位置变化.

Starting from the university physical sensor experiments and taking the application of photoresistor as an example,the characteristics of photoresistor under bright and dark light was designed and studied.The effect of“lighting on at night,not bright during the day”for street lamps was simulated.A demonstration device for automatic tracking of light sources was made.The solar panel symmetrically installed with four photoresistors was placed on the two-dimensional rotating pan/tilt.In manual mode,the rotation of the solar panel could be adjusted by pressing the buttons.In automatic mode and low light environment,the position change of mobile phone point light source could be automatically tracked.
