Applications and Circuits of Photoresistors
Photoresistor is one of the photoelectric sensor elements, which is a kind of element made by the photoconductivity effect of semiconductor. The resistance value changes with the intensity of the incident light. Generally speaking, the incident light increases, the conductivity increases, and the resistance value decreases. Generally, the photoresistor body is made into a thin film structure to absorb more light energy. The material used for the photosensitive layer of the photoresistor can be polycrystalline material or single crystal material, and single crystal material can be made into intrinsic type and Doped type.
