Reply To: Keller CTD Sensor

We haven’t used that sensor at Stroud, but after looking at the spec sheet, I don’t see why it wouldn’t work with one of our newer Mayfly models that generates 12v.  You’ll need a Modbus interface if you want to use that protocol, so either building your own or using the one we’ll be releasing soon.  For SDI-12, it should work directly connected to the Mayfly, though you might need to level-shift the data line.  But the software-side of things is a question for @srgdamiano since she’s the one who writes the libraries and code for all the Modular Sensors stuff.
