Can you email me at mayfly@envirodiy.org, I have a few other questions about the software libraries and hardware combinations for your setup.

Unfortunately, we do not have any other boards. Would it be worth it to purchase a new one? Or is there more troubleshooting we could do with the current setup?

Do you happen to have a spare Mayfly board, or any other Arduino-type board that you could run the sketch on?

Hi Shannon, thank you again. We were finally able to get a voltmeter and test the connection. There is voltage being applied to the sensors when the channel scanning sketch is running, but the program still says no sensor detected and to check the physical connection. We have tested both sensors. Could there be an issue with continuity?

The warnings you posted above seem to indicate that there’s a clash with the Sodaq DS3231 library.  Did you by chance happen to install that library separately into your Arduino/libraries folder?  ModularSensors already includes its own version of the DS3231 library which will conflict with the Sodaq library if they both exist on the same computer.

I have modified the sketch by replacing the UUID list in the original NoCellular sketch with my UUID list from Monitor My Watershed.

Are you trying to use the that NoCellular sketch as-is, or have you modified it before attempting to upload it?

I am using Arduino 1.8.19

I checked the libraries using your method and I do see all the examples and the sketches under the ModularSensors list.

I now ran into another problem which I believe is related to the DS3231 clock. I was able to set the time correctly using the directions from this page – 4. Preparing the Mayfly Data Logger – E…[Read more]

The unzipped folders go into your MyDocumenrs/Arduino/libraries folder.  Make sure they aren’t nested within a second ‘libraries’ folder within the first one.  What version of the IDE are you using?

A good way to check that your libraries are installed correctly is to look at the built-in examples.  In the ARduino IDE, go to the File dropdown me…[Read more]

Yes, I believe I have. It looks like I downloaded all recommended EnviroDIY libraries (47). Do I need to do anything with them once I have them in my library folder? Do I need to install all of them in Arduino somehow?

Have you installed all the supporting libraries into your Arduino/libraries folder?  There should be either 32 folders worth of libraries, or 47, depending on whether you downloaded all the recommended EnviroDIY libraries, or just the ModularSensors dependencies.

Have you tried measuring the voltage being applied to the sensors by using a voltmeter when the channel scanning sketch is running?  For the turbidity sensor’s screw terminal board, put the voltmeter’s red probe on either of the V+ screws, and the black probe on either of the GND screws.  For the CTD sensor’s 3.5mm headphone jack adapter board p…[Read more]

Hello, we’ve returned to try and set up the two sensors again but are still running into the issues of both being vacant at every location. We have tried both of them individually and have changed the 3.3v position to the 12v position for the Clarivue sensor. The Hydros is still connected to the 3.3v. We have also changed the sketch for the…[Read more]

@d_manning just wondering if you have had any insights 🙂
