Welcome to EnviroDIY, a community for do-it-yourself environmental science and monitoring. EnviroDIY is part of WikiWatershed, an initiative of Stroud Water Research Center designed to help people advance knowledge and stewardship of fresh water. We downloaded them on Dec. 1 2025 and we had to let Penn State IT department download them because I am using a PSU computer. I have a feeling that PSU firewall or IT security may be part of the issue.
The Mayfly board we have is distinctly different from the board in the video. We have version 1.1 revision B board # 25069. When we try to put in the UUI for data sets for the conductivity probe we get a compiling error message at the very last step. I did not post this on the forum yet because I suspect we have a newer version of the board. Any help would be appreciated.
Thanks Mark
