Luna Optoelectronics' Cadmium Sulfoselenide (CdS) sensors are low cost photo-conductive devices for visible light measurement designed to sense light from 400 to 700 nm. Their resistance decreases as the light level increases with efficiency characteristics similar to the human eye. These light dependent resistors are available in a wide range of resistance values. They are packaged in a two leaded plastic-coated ceramic header.
