It will be interesting to see how well your ph probe holds up.

Oooh and whislt I think of it, be careful with the pH probe, this really wants a 5v supply to it (even tho it tells you 3.3-5.5v). The MKR1300 pins are only 3.3v tolerant, anymore than this and you are going to let the magic smoke out at worst.

Dont forget with your

Water TDS
Water PH

you will want to pass the water temp to the respective functions to get stable and accurate readings. Looks like you are using the DFRObot pH probe, will be interested to see how you get on with this. From the data sheets its ideal temp for measurement is 25C, what I am monitoring is no where near this, so spending some time with math.h to try and get better (more accurate) measurements.
