Reply To: Inexpensive DIY conductivity sensor

Hi Robert,  I really like your Continuous Logger Post and the installation detail.

I’d be happy to share what I’m doing, and I’ve just finishing up a ModularSensors class last week.

just thought I had posted here, and it hasn’t shown up, so trying again – here are the core details

https://github.com/neilh10/ModularSensors/blob/rel1_dvlp1m/src/sensors/analogElecConductivity.cpp

Comments and code review welcome.

Its using an analog port, per the original post, and powered by a toggling port bit.

The actual target is a “Relative EC” as a “Stream Disconnect Sensor”

so I’m not paying attention to the units of measurement, though still calculating them as uS/cm2
