Hello good day! I need a simple circuit to detect the turbidity of
the reuse water from the washing machine, that is, discard the 1st
water and reuse the others, a very simple circuit for a low-income
community. Thank you Marcos

On a good day, you can measure the turbidity using an Arduino, a LED, a
phototransistor, and a resistor.
The problem normally has more to do with how to keep the optical window
clean.(*) That might be easier with a clothes washer, because the flow
is pretty strong and frequently has a lot of detergent and bubbles,
which should help.
It\'ll need some experimenting, though.
How high-tech is your setup? I assume you have a storage tank, but how
does the water get in and out, and how is that controlled?
Cheers

(*) If you have the time, and a nearby library can get a copy, Mark
Johnson\'s \"Photodetection and Measurement\" is an excellent read. Mark
was the head of quality assurance for a bit water utility in England,
and really knows turbidity measurements. A lot of it is quite
accessible at hobbyist level.
