NTE Popular line of Light Dependent Resistors ( Photoconductive Cells) includes higher power 12mm and 20mm types. LDRs are made of a kind of semiconductor material with conductivity characteristics that change with the illuminance change. Small devices use low-power and are easy to use and do not wear out. Devices are sometimes referred to as CdS cells since they are made of Cadmium-Sulfide. Typical applications include: ambient light detecting; camera auto exposure control; backlight control; light adjusting applications
