Hi Shannon,
Thank you for the response. I ran the board attached to my computer in Arduino and the red LED3 light did come on when the sample was run. I put a voltmeter across the GND and V pins and the voltage was 3.3v when the sample was collected.
The sketch on the 0.5b board is older than 2022 so that would explain why the new Gen2…[Read more]

All Mayfly logger board from version 0.3 to the current v1.1 (and including your v0.5v) have a separate 3.3v regulator that powers external sensors, and also the 5v boost circuit. This secondary 3.3v regulator is turned on or off by controlling pin D22. When the regulator is turned on, a red LED in the lower left corner of the Mayfly should t…[Read more]

Hello,
We have a Mayfly station with a version 0.5b board and a Hydros21 CTD sensor attached. The sensor had been working for years at the site but recently, the CTD measurements were being reported as -9999 for all three parameters. I tried troubleshooting and ended up swapping out the sensor for a new Hydros21 CTD sensor. Before deploying, I…[Read more]

Hello Kara, as someone who works with TU Mia and Troy in California, and deployed a number of systems north of San Francisco there are a few items to note.
From the description, you will need all the C++ code – the Arduino sketch , and tools setup. You might want to reach out to the original project and see if they have that code, and if it…[Read more]

Hi Shannon,
Thanks so much for all the help, these were originally purchased by my organization in partnership with Trout Unlimited. TU did all the preliminary set up so the manuals I had on hand only covered field installation and troubleshooting.
It looks like we have Mayfly version V1.0 (according to our manuals) and our cell board is the…[Read more]

If you are physically relocating a monitoring station that reports to MonitorMyWatershed (MMW) then it’s best to create a new site instance on MMW for the new station. That way all the old data that was collected at the original location will still show up on the map at the original location. If you edit the MMW location for an existing site, t…[Read more]

Hi all,
I am trying to relocate my data loggers to new locations to monitor water quality at a restoration site. These data loggers have been used in the past at separate project sites and I have several questions about updating these to the new sites.
