NSL-5542 Luna Optoelectronics

Light dependent resistors are two cadmium sulphide (cDS) photoconductive cells with responses similar to that of the human eye. The cell resistance falls with increasing light intensity.

Solid-state photosensor that uses photoconductivity to lower resistance value when irradiated with light
