DFRobot Gravity - analogue turbidity sensor

A sensor that tests water quality by determining the level of turbidity. It detects particles suspended in water by measuring light transmittance and propagation rate, which changes as the total suspended solids (TSS) increases. The greater the TSS, the greater the turbidity level.

Turbidity sensors are used, for example, to measure water quality in rivers, streams, to measure wastewater and in laboratory instruments.
