Cadmium sulfide (CdS) photodetectors, also known as photoresistors, light-dependent resistors (LDRs), or photo-conductive cells are high resistance semiconductors that operate as light-controlled variable resistors. The resistance of a photoresistor decreases with increasing incident light intensity. Photoresistors are selected by cell resistance, max voltage, and rise and fall times.
