This is low cost LDR (Light Dependent Resistor). Basically it is a light sensitive resistor, the resistance will decrease when the surface is expose to light. It is widely used to detect Day or Night, example in automatic car porch light. It is nonlinear sensor, when it is not expose to light, the resistance can goes up to 500K ohm, but from our testing, in normal room conditions, it will be 10 to 20K ohm when it is dark. When a light is activated, the resistance drops to 1K or less.
