The Grove turbidity sensor measures the turbidity of the water (the number of suspended particles). The optical sensor of this module can measure the density of turbid water and the concentration of extraneous matter using the refraction of wavelengths between the phototransistor and diode. By using an optical transistor and optical diodes, an optical sensor measures the amount of light coming from the source of the light to the light receiver, in order to calculate turbidity of water. 

The output mode can be selected by adjusting the switch on the board. Supports analog and digital output. The sensitivity can be adjusted by the on-board knob. Some typical applications of this sensor include:

  • Measuring the level of water pollution in washing machines such as dishwashers to determine the optimal washing time and rinsing times.
  • Industrial site control.
