The turbidity sensor for arduino can detect the water quality by measuring the level of turbidity
The principle is to convert the current signal into the voltage output through the circuit. The lower the output voltage is, the higher the turbidity value.
Its detection range is 0%-3.5% (0-4550NTU) , with an error range of ±05%F*S.
Do not completely immerse the sensor in water. Just measure the small round head of the split parts into the water and measure it. The top of probe is not waterproof.
