The Aanderaa Turbidity sensors detects infra-red light scattered by particles suspended in water.
This measurement is known to have a good correlation to the amount of suspended matter in water and can be used to monitor e.g. sediment, algae or particle pollution. The Turbidity sensor generates an output voltage proportional to the turbidity or suspended solids. The low power consumption makes the Turbidity sensor ideal for applications where battery drain is a concern.
