Photoelectric sensor is analog measurement will be converted into changes in the photocurrent row, and it was measured with single-valued relations between. Analog is measured by photoelectric sensor (object detection) transmission methods can be divided into (absorption) -, diffuse reflection, absorption - (beam resistance files) three categories. The so-called transmission-means-tested objects on the road, a constant source of light energy through the measured object, most of the absorption, optical transmission project to optoelectronic components; The so-called diffuse reflection is a constant source of light projected on the measured object, from the detected objects to the surface after projecting optoelectronic components; Shade refers to the so-called when-issued light of the flux measured by the light of a cover part of the projected cut optoelectronic components of flux change, and the degree of change in the optical path detected objects on location
