Description
A turbidity sensor measures the clarity of a liquid by detecting how much light is scattered by suspended particles in the fluid. The greater the number of particles present, the more light is scattered, resulting in a higher turbidity reading. Turbidity is typically expressed in NTU (Nephelometric Turbidity Units). These sensors are widely used in water quality monitoring, helping assess contamination levels, sediment concentration, and the effectiveness of filtration or treatment processes.
