| VISIBLE DETECTOR CdS photoconductive cell Resin coating * dual type Low cost dual-element sensor with standard size CdS photoconductive cells utilize photoconductive effects in semiconductors that decrease their resistance when illuminated by light. These sensors are non-polar resistive elements with spectral response characteristics close to the human eye (luminous efficiency), thus making their operating circuits simple and small. Dual-element sensors can be used to compare the signal from each element or perform signal processing by using a separation circuit.
