光敏电阻器是利用半导体的光电效应制成的电阻器,其阻值随入射光强弱的变化而变化。光敏电阻器主要有三大类型:紫外光敏电阻器、可见光敏电阻器和红外光敏电阻器。实际应用较多的是可见光敏电阻器,主要用于各种光电自动控制系统,如航标灯、路灯及其他照明系统
Photoresistor is the use of the photoelectric effect of semiconductor resistors, the resistance changes with the intensity of incident light changes. There are three main types of photosensitive resistors: UV photosensitive resistor, visible photosensitive resistor and infrared photosensitive resistor. The practical application of more visible photoresistor, mainly for a variety of photoelectric automatic control system, such as beacon lights, street lights and other lighting systems
