Hi @Walter, I completely missed this turbidity question. We have used Yosimetech (http://www.yosemitech.com/en/) turbidity sensors, but there’s enough hassle in ordering (customs hang-ups every time) and creating a RS-485 shield to communicate with those, that going with the Campbell sensor might be in my future.

I haven’t deployed an OBS, but it looks like it goes into the I2C port using the instructions at:
https://github.com/EnviroDIY/ModularSensors#campbell-scientific-obs-3
where it says that, “The power supply is connected to the red wire, low range output comes from the blue wire, high range output comes from the white wire, and the black, green, and silver/unshielded wires should all be connected to ground.”
