[0002] Currently, turbidity sensors can detect the turbidity value of water in cleaning equipment and automatically set the cleaning equipment according to the detected turbidity value. When the detected turbidity value is high, it means that the cleaning items are dirty, and the cleaning frequency and time can be increased to ensure the cleaning degree of the items. Existing turbidity sensors have complex structures, are difficult to install, and are expensive.
