Pro-Range 70 PCS Photoresistors Kit

Photoresistors, also known as light-dependent resistors (LDRs), are electronic components that change their resistance in response to changes in the intensity of light. They are made of semiconductor materials such as cadmium sulfide (CdS) or lead sulfide (PbS) that have high resistance in the dark and low resistance in the light. When light falls on the surface of the photoresistor, the photons in the light excite electrons in the semiconductor material, causing them to move and reducing the resistance of the material. The amount of resistance change depends on the intensity of the light, with brighter light causing a greater reduction in resistance.
