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]

From your error messages, it looked like you have mismatched versions of libraries.  I’m not sure how permissions are set up on your PC, but typically the Arduino libraries would be stored in a personal user folder that you could change at…[Read more]

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.

I personally haven’t used any Sandisk Ultras with our loggers, so I can’t say how it performs.  This guy did a really great test last year with a variety of microSD cards and summarized his findings (particularly on idle current) in a really helpful list:  https://neurotechhub.wustl.edu/micro-sd-card-low-power-showdown-part-ii/

Have you had success with the Sandisk ultras? https://www.bhphotovideo.com/c/product/1593899-REG/sandisk_sdsqua4_032g_an6ia_imaging_ultra_32gb.html

Looks like they are the next step from the basic Sandisk. thanks

Genuine Sandisk and Kingston cards have served us well, not drawing excessive power when the board is sleeping, and being reliable over many years in field deployments.  What we’ve seen issues with is generic cards from random manufacturers because they either fail and corrupt the data after a short time, or they draw 5 or 10 times more power…[Read more]
