This cadmium sulfide (CdS) light dependent photo resistor has resistance inversly proportional to the amount of light falling on it. In complete darknes it has a 0.2 M ohm resistance and in 10 Lux light it has approximately 10 K ohm resistance.
Great for light sensor electronic circuits, for Arduino modules, robots, and more.
