According the Light scattering theory, the scattering of light was thought of as the redirection of light that takes place when an electromagnetic wave (i.e. an incident light ray) encounters an obstacle or non-homogeneity, the turbidity concertration is directly proportional to the scattering of light, when the light go through the liquid, as this theory. The turbidity sensor directs a focused beam into the monitored water, The light beam reflects off particles in the water, and the resultant light intensity is measured by the turbidity sensor's photodetector. The light intensity detected by the turbidity sensor is directly proportional to the turbidity of the water.
