LDR 12mm - Light Sensitive Resistor

The LDR 12mm, also known as a Light Dependent Resistor, is a type of photoresistor. Photoresistors are unique electronic components that exhibit a resistance that varies based on the intensity of light they are exposed to. The LDR is constructed from cadmium sulfide (CdS), a semiconductor material with the ability to absorb photons of light.
