Description
Cadmium Sulfoselenide (CdS) sensors are low cost photoconductive devices for visible light measurement. Their resistance decreases as the light level increases with efficiency characteristics similar to the human eye.
The GM45 Series are (CdS), Photoconductive photocells designed to sense light from 400 to 700 nm. These light dependent resistors are available in a wide range of resistance values. They’re packaged in a two leaded plastic-coated ceramic header.
