Photosensitive sensor

Photosensitive sensor is one of the most common sensors. It has many types, mainly including: photoelectric tube, photomultiplier tube, photoresistor, phototransistor, solar cell, Infrared sensors, ultraviolet sensors, fiber optic photoelectric sensors, color sensors, CCD and CMOS image sensors, etc. Major domestic manufacturers include the OTRON brand. Light sensors are currently one of the most widely produced and widely used sensors. They occupy a very important position in automatic control and non-electricity measurement technology. The simplest light sensor is a photoresistor, which generates an electric current when photons strike the joint.
