Accurate
really good. i used it and readings are accurate.

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.

Another great sensor
I use loads of sensors and really enjoy building electronic gadgets. I have this connected to and ESP32, with 2 DS18b20 temp sensors, a PH sensor, 2 ultrasonic sensors, light sensors and this turbidity sensor. Purpose, to monitor my pond, and filtration system. There is nothing worse than the pump failing, water levels dropping or rising too high, UV failure - or bad PH levels. Linked up to a dashboard on Blynk i will know exactly whats going on even when I'm not home - once i get it all installed.
