Device works nice. No complaints
This is basically the exact same part you'll see in the bottom of your dishwasher, but broken out for generic usage. Device works nice. No complaints, and there's documentation floating around on the internet about it.

Turbidity meter use
I was hoping to use for reasonable turbidity reading for nearly clear lake water. Inaccurate at low levels and reading drifts.
