摘要

光传感器是一种利用光敏元件将光信号转换为电信号的传感器。它的敏感波长接近可见光波长，包括红外波长和紫外波长。光传感器不仅局限于光检测，还可以作为检测元件组成其他传感器，只要将这些非电转换为光信号的变化，就可以检测到许多非电。

光强自动检测显示系统，可自动检测光强，显示此时的光强。人们可以设定光强的范围，系统一旦超出这个范围，就可以发出报警通知或直接采取措施，使光强在这个范围内。人们可以通过查看该装置的显示来了解当前的光状态，并进行合理的光调节。该设计可分为三检测、信号处理和光强显示三部分。还可加上报警部分。光敏电阻传感器可作为光检测部分的检测元件，可完成从光强到电阻值的信号转换，然后将电阻值转换为电信号作为系统的输入信号。处理输入信号后，可用于显示。发光二极管可用于显示部分，不同的光强对应于不同的发光二极管，可以简单地显示不同的光强。

The light sensor is the use of photosensitive element will be optical signals are converted to electric signals of sensors, its sensitive wavelength in the visible light wavelength near, including infrared wavelength and ultraviolet wavelength. The light sensor is not limited to light detection, it also can be used as detection components other sensors, for many non-electricity testing, as long as these non-electricity conversion for light signal can be change.

Light intensity automatic detection display system, this system can automatically detect the intensity of illumination intensity and display to let people know the strength of the light intensity at this time. People can be set illumination intensity range, once beyond this range the system can issue warning notice or directly to take measures to make the light intensity in this range. People can see through this device display learn now light condition, to do a reasonable light regulation. This design can be divided into three parts: namely light detection part, signal processing part, intensity of light display section. Still can add alarm part. For light detection part available photosensitive resistance sensor as the test components, it can complete from intensity to resistance signal conversion, again resistance are converted to electric
