Circuit Modules & Development Board
Principle: Turbidity sensor TS-300B measures the turbidity (counter of suspended matter) in the wash water. Based on the optical principle, the sensor uses the light-emitting diode and phototransistor to receive the specific wavelength to measure the opacity or other substances of dirty water. conc..
