Gravity Analog Turbidity Sensor

The analog turbidity sensor for Arduino detects water quality by measuring the degree of turbidity, which changes with the amount of suspended matter in the water. The higher the TTS value, the higher the turbidity level of the liquid. The sensor has both analog and digital signal output modes, with the threshold adjustable in digital signal mode. Turbidity sensors are used to measure water quality in rivers and streams, sewage and wastewater measurements, sediment transport research, and laboratory measurements.
