A line of cadmium sulfide (CdS) light-dependent photoresistors is designed to sense light from 400 nm to 700 nm; their resistance decreases as the light level increases, representing the efficiency characteristics of the human eye. The photoresistors, which are available with various resistance values and packaging, have multiple uses, including street and solar lighting, audio compression and flame detection, camera light meters, and exposure and shutter controls applications.
