Curious what it would take to integrate this TDS meter into the reef angel.
Some examples of code on the wiki.

You would need an ADC chip that communicates using I2C. All of our expansion modules use I2C.
Just need to find one that is not used by your system.
If you want to hack it, any expansion module would work for you.
But I think the multi-channel water level would work best as it has 4x ADC's, so you could have one before the RO and one in between RO and DI and one after DI.
I can sell you the board without the pressure sensors. Send me a PM if you want to do that.

Awesome! I’m going to order one of these boards and currently have a water level sensor hanging around unused to try it out. If it does work I will certainly order the 4 channel unit. I’d likely need 4 channels.
I’m hopeful the probe will work in a pressurized system. Everything shows it just sitting in a glass of water.
Thanks
