Classification of photosensitive sensors
Photosensitive sensors are one of the most common sensors. They are mainly used in: photocells, photomultiplier tubes, photoresistors, phototransistors, solar cells, infrared sensors, ultraviolet sensors, fiber optic sensors, color sensors, CCDs, and CMOS image sensor, etc. Major domestic manufacturers include the OTRON brand. Light sensor is one of the most widely used and widely used sensors, and it plays an important role in automatic control and non-electrical measurement technology. The simplest photosensor is a photoresistor that generates current when the photon impacts the junction.
