Improving on HydroBuddy’s theoretical conductivity model, the LMCv2
Hydrobuddy’s theoretical conductivity estimates have never been good. As I discussed in a previous post, the program uses a very simple model based on limiting molar conductivities to calculate the…

Creating a pH/EC wireless sensing station for MyCodo using an Arduino MKR Wifi 1010
There are multiple open-source projects available online for the creation of pH/EC sensing stations for hydroponics. However, all of the ones I have found use a single Arduino or Raspberry…
