Hi @Selbig. Here is a very simple sketch that prints a file from the microSD card to the serial monitor. It might be too rudimentary for your purposes, but thought I would share it here. Notice the line “// SD.remove(“datalog.txt”);” is commented out. Uncomment this line to DELETE the file specified instead of printing it to the serial monitor. I…[Read more]

Fiona, if you haven’t already found it, check out Adam Gold’s blog about using the Mayfly with Atlas Scientific sensors. Adam’s github has documentation about a carrier board that may involve isolation.

Hi Dan,

We recently did some internal testing of this issue and will post results soon. We don’t have a “fix”, but we did measure this behavior to guide our own interpretation of data.

<p class=”crayon-selected”>Hi James,</p>
I’ve used Atlas Scientific’s RGB sensor on lagrangian river drifters in the past. The application is written up in Limnology and Oceanography (or see this video abstract of the article). I’m attaching two simple sketches for using this sensor with the Mayfly Data Logger. The first (…AutoMode) just prints…[Read more]

Thanks, Neil. That’s helpful to know that ThingSpeak via Modular Sensors might be a better option for this user’s purposes. He has an interesting classroom laboratory application that I’ll encourage him to share if he is able to pilot it at his college.

Hi Jim: I haven’t been following this thread but I’m excited that you are pushing through this to get your data streaming to MonitorMyWatershed! I’m glad Sara has been providing help. It occurred to me that you might reach out to Adam Gold (@adamgold) because he was using both Atlas Sci hardware and PlatformIO. He published a blog detailing his…[Read more]

Hi Oscamo. Indeed, I was formerly at Planktos Instruments but now at the Stroud Center. In responding to Sara’s comment about trajectory data being hard to visualize, check out this video showing dissolved oxygen data along 22 miles of the Neuse River in North Carolina.

We’ve been collecting trajectory data with drifter technology here at the…[Read more]

Sensors, no. Autonomous orthophosphate wet chemistry, yes. Check out Green Eyes Science’s NuLab (http://gescience.com/nulab/) and Seabird’s hydrocycle (https://www.seabird.com/hydrocycle-po/product?id=54721314201). There are others out there, but these come to mind first.
