Courtesy of Sparkfun Electronics - Hello, and welcome to another edition of Masterpiece Theater Engineering Roundtable. This time around, SparkFun engineer Joel walks us through the steps to make a nifty handheld pH sensor, which he uses to regulate his home aquaponics system.

 

The schematic and code for the H2O pH Probe can be found at the GitHub repository here, and the wishlist for the parts Joel uses in his project is below. As always, if you have any questions or suggestions for this or future projects let us know in the comments, and we’ll see you next time!
