Introduction to turbidity sensor:The turbidity sensor USES the optical principle to comprehensively judge the turbidity by the light transmittance and scattering rate in the liquid solution. Since the turbidity value is an asymptotic variable, it is usually detected in a dynamic environment.Therefore, the sensor also needs to make peripheral circuit to detect in the system, with a waterproof probe, mainly applicable to washing machines, dishwashers and other equipment turbidity detection, can also be used in electronic design, graduation design, electronic competition experiments and other applications.
