Photoresistor, also known as a light-dependent resistor (LDR), is a type of variable resistor whose resistance changes based on the amount of light falling on it. It is made from semiconductor materials, typically cadmium sulfide (CdS), which exhibit photoconductivity. This means that when light strikes the surface of the photoresistor, the material's ability to conduct electricity increases, and its resistance decreases.
