Photoresistor is a resistor made of a semiconductor material the conductivity change with changes in illumination. With this feature the light of different shapes and areas of the photoresistor. Photoresistor is widely used in toys lamps cameras and other industries. Performance and Features Epoxy resin good reliability small size high sensitivity fast response speed good spectral characteristics Applications The camera automatically metering photoelectric control interior light control alarm industrial control light control switch light control lamp electronic toys
