Photosensitive resistor details

Photosensitive resistor is made using the photoelectric effect of the semiconductor a resistance change with the strength of the incident light and the resistor; The incident light intensity, resistance is reduced, incident light is weak, resistance increased. Edit this section Photoresistor light measurement, the light is commonly used in control and photoelectric conversion would change (changes in the light into electricity). Commonly used photoresistor cadmium sulphide photosensitive resistor, it is made of semiconductor materials.
Photosensitive resistor of resistance change with the strength of the incident light (visible light), under the condition of dark, its value can be up to 1 ~ 10 m (dark), under the strong light condition (100 lx), its value (bright resistance), only a few hundred to thousands of ohm. ? photoresistor light
