By detecting the degree of turbidity, the Keystudio turbidity sensor assesses water quality. The concept is to use the circuit to transform the current signal into a voltage output. It has a detection range of 0.5%-3.5% (0-4550NTU) and an error range of 5%F*S. When utilizing, measure the voltage value of the sensor’s Signal end and then use a simple mathematical technique to calculate the turbidity of the water.

This turbidity sensor may produce both analog and digital signals.
A sliding switch is included with the module. When the switch is moved to the A position, connect the signal end to the analog port, and read the analog value to compute the output voltage to determine the turbidity of the water. If you connect the signal end to the digital port and slide to the D end, you can detect turbidity in the water by producing a HIGH or LOW level.

You may modify the sensor’s sensitivity by using the blue potentiometer on the sensor. Turbidity sensors can be used for river and stream water quality measurements, wastewater and effluent measurements, sediment transport investigations, and laboratory measurements.
