摘要
光敏电阻是一种把光照强度变为电信号的传感器。拓展了光敏电阻的另一种工程应用,用其检测太阳能板集能元件的效率。研究灰尘和光照强度与敏感元件电信号间的关系。通过大量实验,在不同灰尘密度下,通过改变光照强度,测量光敏电阻的电压,并且用PHOTOSHOP软件量化灰尘密度,应用MATLAB软件建立光敏电阻电压与灰尘密度、光照强度的三维模型。用此模型可以研究集能元件的效率。
The photoresistor is a kind of transducer which turns light intensity into electric signal. This paper extended another enginering apply of the photoresistor, which can be used to detect the efficiency of solar panel＇s energy receiving element,and research on the relation among dust, light intensity and sensitive element＇s electric signal.Through a great deal of experiments,measuring the voltage of photoresistor in different dust density by changing the intensity of light and quantifying the dust density by PHOTOSHOP, then the 3D model of the photoresistor＇s voltage,the dust density and the light intensity which build by MATLAB.We can study the efficiency of energy receiving element by this model.
