Working principle
The scattering turbidity sensor determines the concentration of particles in a liquid by measuring the scattering of light. It uses a light source to illuminate the liquid and then measures the scattered light intensity at different angles. This sensor adopts the 90 ° angle scattered light method, linearly processes the collected values, and outputs turbidity values through temperature compensation algorithm.
