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]

How and when did you download all of your libraries?

Hi, I’m ready to get my sensors out for this year to start data logging, but I’m stilling having the interval reporting issues with both the CTD and ClariVUE10 sensor. Could the libraries be causing these issues? Are the three sensors, CTD, ClarieVue10, and C-FLUOR Phycocyanin overloading the logger? Is there an updated libraries available? I’m…[Read more]

I forgot, there is also a documentation page here: https://www.strawberrycreek.org/night-heron-docs/

Hi Scott,

Yes the Alarm System in running quite well. We actually just caught a broken fire hydrant discharging upstream of one of our mayfly stations with it an hour ago. I’ll check out the repo to see if there’s anything that could benefit the alert system!

I have a paper that talks bout some of the anomaly detection methods I’ve been working…[Read more]
