Photoelectric effect refers to the phenomenon that when light shines on certain materials, the electrons of the material absorb the energy of photons and the corresponding electrical effect occurs. According to the different phenomena of photoelectric effect, photoelectric effect is divided into three categories: external photoelectric effect, internal photoelectric effect and photovoltaic effect. Photoelectric devices include phototubes, photomultiplier tubes, photoresistors, photodiodes, phototransistors, photocells, etc. The performance and characteristic curves of photoelectric devices are analyzed. Photoelectric sensors are controlled by converting changes in light intensity into changes in electrical signals. Photoelectric sensors are generally composed of three parts, which are divided into: transmitter, receiver and detection circuit. The transmitter aims at the target to emit a light beam, which is generally derived from a semiconductor light source, a light emitting diode, a laser diode and an infrared emitting diode. The light beam is emitted continuously or changes the pulse width. The receiver is composed of a photodiode, a phototransistor and a photocell.
