Product details
one.Self-cleaning Turbidity Sensor working principle
Self-cleaning Turbidity Sensor adopts optical technology, with automatic cleaning brush, integrated design, has strong anti-interference ability and is free from maintenance.The Self-cleaning Turbidity Sensor determines the concentration of particles in a liquid by measuring the scattering of light.It uses a light source to shine into a liquid and then measures the scattered light intensity at different angles.This sensor uses the 90° angle scattered light method to linearly process the collected values, and outputs turbidity values through a temperature compensation algorithm.
