Sensor overview

Oct 01, 2019

The photosensor generally consists of a processing path and a processing element 2 portion. The basic principle is based on the photoelectric effect, which converts the measured change into a change of the optical signal, and then further converts the non-electrical signal into an electrical signal by means of the photoelectric element. Photoelectric effect refers to the illumination of an object by light. It can be seen as a series of photons with a certain energy being bombarded on the object. At this time, the photon energy is transmitted to the electron, and the total energy of a photon is once The electrons are absorbed, and the state of the electrons is changed by the energy transmitted by the photons, so that the objects irradiated by the light have corresponding electrical effects.
