Great suggestions and tips, thanks Rene! I’ll put some extra time into designing the implementation of that turbidity sensor, I have a few ideas but zero experience with actual tests. I assume the same issues apply, maybe more so, with cheap flow rate sensors like this: https://thepihut.com/products/adafruit-liquid-flow-meter-plastic-1-2-nps-threaded

I would imagine they may provide some initial indication of flow but shortly after are almost useless due to deposition/foul.

Temperature by itself can be pretty useful though, so I’ll start there.

Good discussion here. @kevin, how did this project end up? Were you able to address data shifts with calibration?

I’m also looking into remote stream monitoring. My particular measurements are water temperature and stream turbidity. The latter I am still struggling with for all reasons mentioned here. Have prototypes in my yard of this all working, but the actual deployment into a stream seems difficult. I am currently debating between a completely submerged control box with an integrated PVC pipe where the sensors would go, or having the main control box above water somewhere with the sensor/pvc system in the stream somewhere. The solar panel would need an extension cord and up into a tree somewhere.

Any tips, updates from those who have already done this widely appreciated. The turbidity sensor I am evaluating is:

Using a standard DS18 water temp sensor.
