The self-cleaning turbidity sensor is designed specifically for long-term stable monitoring of water turbidity. It uses optical scattering principle to accurately capture suspended particulate matter content in water, and integrates automatic cleaning brush and anti adhesion coating to regularly or on-demand remove surface dirt from the sensor, avoiding measurement errors caused by impurity deposition. It has a high protection level and is suitable for complex environments such as sewage, surface water, and industrial wastewater. It supports analog or digital signal output and real-time data transmission to the monitoring system, helping users efficiently grasp water quality changes, reduce manual maintenance costs, and improve monitoring reliability.

Oneworking principle
Self cleaning turbidity sensorDetermine 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.
