基于单片机的光照度传感器设计-毕业设计
本设计采用光敏电阻为光传感器,光敏电阻阻值随光照强度的变化而变化(入射光强,电阻减小;入射光弱,电阻增大),利用光敏电阻的光照特性完成光强的检测。该设计可分为三部分:即光照检测部分、信号处理部分、光强显示部分。具体方法是将光敏电阻与一定值电阻串联接入电路,光照强度的变化会引起光敏电阻阻值的变化,从而影响电路电流及电压值的分布,将模拟电压通过ADC0804模数转换器转换为数字电压,通过VC语言编程,将其集于单片机AT89C51中进行处理,并将其通过液晶屏显示出来。本设计电路结构简单,成本相对较低,通过对光敏电阻阻值的变化的运算处理,从而检测不同的光照强度,实用性较强。
