Turbidity sensor TS-300B is used to measure turbidity in washing water (suspended matter counter). Based on optical principle, the sensor uses light-emitting diodes and phototransistors to receive specific wavelengths to measure the opacity of dirty water or the concentration of other substances. By using phototransistors and light-emitting diodes, the light emitted by the sensor through the light source of light-emitting diodes is reflected by sewage, and part of the light is transmitted to the phototransistor. According to the amount of light received, the turbidity of water is calculated.
How the KIE turbidity sensor works: When light passes through a certain amount of water, the amount of light that penetrates depends on the amount of dirt in the water. When the amount of dirt increases, the light that penetrates the water sample decreases, and the turbidity sensor measures the amount of light that passes through to calculate the turbidity of the washing water.
The turbidity sensor provides these turbidity measurements to the washing machine or dishwasher controller, which determines the time of each washing cycle. These judgments are based on the comparison between the measured values of clean water (measured at the beginning of the washing cycle) and the measured values of washing water measured at the end of washing.
By measuring the turbidity of the washing water, the washing machine can save energy by washing only the time needed when washing non-dirty clothes, so that end users save energy.
