Cadmium Sulfide (CdS) Light-Dependent Resistors (LDRs) from Advanced Photonix Inc. are designed for visible light measurement from 400 to 700 nm.

CdS photoresistors can be used for street and solar lighting, audio compression and flame detection, camera light meters, and exposure and shutter controls applications. The photoconductive devices’ resistance decreases as the light level increases, representing the efficiency characteristics of the human eye. The photoresistors, or photocells, are available with various resistance values and packaging. They can also be utilized in clock radios, alarm devices, outdoor clocks, and night light controls.
