Hi,

I suggest you measure the voltage on the OUT pin of the turbidity sensor on clear water and muddy water. Then determine the adc values using the formula on the article. Then, change this part of the code to the results of the formula:

turbidity = map(val, 0, 2800, 5, 1);

Here, 2800 was my adc value at muddy water
