Main Features:
1. Using photoelectric effect of semiconductor to make a resistance value that the resistor changing with the intensity of incident light
2. Strong light, impedance reduces
3. Weak light, impedance increases
4. For all kinds of light control products, such as night light, solar light, light control toy, e-Book, banknote detector, CCTV camera, professional speaker
