    Have you discovered any sensors for pH, Temp, DO, and Conductivity since your post last year?

    • yes, I have been using Atlas Scientific sensors. They have very good customer support. Always willing to help.
      I have duplicated my setup and now have three separate sensor sites all loaded with Atlas sensors. Make sure to use EZO carrier boards, sensor circuits, and the probes-all from Atlas. Call them up-they will explain all to you in detail.
      I also have Global Water sensors but they work off of 12 V supply. I haven’t tried using Global sensors (or any that require 12 V) on Mayfly boards but I was told that there is a way to do it by using a booster that goes from 5V to 12 V. You have to flip the switch on Mayfly (lookup schematic for version 0.5-it’s within the blocked labeled 3.3 V) and output 5V. Hope that helps.
