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

[Shannon Hicks]

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

[Shannon Hicks]

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.

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

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 menu, then select examples.  You should see the basic Arduino example, then some more complex ones, but keep scrolling to the bottom and you should see lots of other ones like Adafruit and ModularSensors and SDI12.  The sketch you’re trying to use should be included under the ModularSensors list.  If you don’t see it, then your libraries aren’t installed correctly.

If your libraries are correct, there should be more information in the error window that will tell you what is causing the problem.  If you still get the error, copy that full error message into your post.

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 put the probes on the two points shown in the attached photo.

In your 4th picture, it looks like the Grove cable plug may not fully be seated in the grove jack.  Not sure about any of the other ones since the angles in the photos didn’t show them well, but be sure that it’s pressed all the way into the jack.  And your second photo shows that your two SDI12 Grove jack voltage selection jumpers are both set to the default 3.3v position.  As stated above, the ClariVue sensor requires 12v to operate, and since you’re not using one of the 12v boost screw terminal boards, (photo 3 shows the standard 6-position multipurpose screw terminal board), then you’ve got to select 12v on the Grove jack where you’ve got the turbidity sensor connected.  Also look at the bottom of the screw terminal board and make sure there are solder blobs on the 3 solder jumpers, all in the default position (there’s a photo of the bottom of the board on the product page, showing the 3 possible solder jumper positions)

I assume you plugged both sensors into the Mayfly for the photo, but remember that you need to fully disconnect one of them if you’re trying to set the SDI12 channel.  The sketch you sent looks like it’s been slightly modified from the original one that’s included in the SDI12 library’s example (which can be found here: https://github.com/EnviroDIY/Arduino-SDI-12/blob/master/examples/b_address_change/b_address_change.ino).  I would recommend you use the original sketch, with only one sensor attached, making sure both ends of the Grove cable are plugged in securely, and that you use 12v on the one for the turbidity sensor.

[Shannon Hicks]

Can you describe how you’ve connected the sensors to your Mayfly, there are multiple ways to do it correctly with the adapters we offer and even more if you’re doing it a non-traditional way.  Better yet, could you take a pictures of your setup showing how you’ve connect each of the sensors to the Mayfly?

[Shannon Hicks]

When the sensor is powered, you should be able to put the two probes of a voltmeter on the little screws on top of the screw terminal board where you’ve connected the ClariVue’s cable to the Mayfly.  Put the black probe on the Gndscrew and the red probe on the V+ screw.   You’ll know the sensor is being powered when the red LED on the bottom left corner of the Mayfly board is lit  (the one labeled Switched Power Out).  You can put the Mayfly into test mode by pressing (for one second) the D21 pushbutton next to the microSD card socket.  That’ll wake the Mayfly (and keep it awake) for a few minutes, constantly keeping the output power on and will also output sensor data to the serial monitor every 10 seconds or so.  Putting it in this mode will give you time to check the output voltage with a meter.
