Description
The Cadmium Sulfide (CdS) or Light Dependent Resistor (LDR) whose resistance is inversely dependent on the amount of light falling on it, is known by many names including the photo resistor, photoconductor, photoconductive cell, or simply the photocell. The photo-resistor finds many uses as a low cost photo sensitive element use in photographic light meters as well as in other applications such as smoke, flame and burglar, detectors, card readers and lighting controls for street lamps.
