Reefpi Update (Raspberry Pi OS (Trixie) 64bit)

[Sral]

Little Update, i finally got the new version of the Robo-Tank conductivity circuit.

I have started to write the driver, i have also added the ability to use a in tank Temp probe for compensation, for those like me that want accuracy.

Robo-Tank conductivity circuit

Nice ! It is basically just the same as the Atlas Instruments one iirc, have to check.

BTW, one can also use Rob's pH circuit to measure ORP, just connect an ORP probe to the board and convert the pH that is returned back to mV and you are golden. Might actually be a great change on Rob's side: expose both values in the interface.

Regarding the temperature compensation:
Are you doing that on the Pi or on the conductivity sensor ?
Strike that, forgot that the sensor probably isn't equipped for that. Does your compensation mean that you have an alpha of 0.001145 or that it's 0.019 plus that value ?
