Where did the calibration coefficients you used in line 31 come from?  They could be in error.  The raw value of adc0 in line 26 is a bit count and 65536 (2^16) is the maximum which would be the value output if the analog input was connected to Vdd (~3.3V).

Don’t know why the zero offset.  I would try printing out your raw adc0 with the analog in…[Read more]

Hi Adam-

Thanks for getting back to me.  Since my software expertise is limited and I don’t understand how all the code in ModularSensors works I have not been able to get “calculated variable” to compile in my simple_logging.ino code.  I have been successful in getting the code to work with external_voltage and the Atlas EZO c…[Read more]

Hi Jim – To get the linear correction, you should be able to make a calculated variable in .ino file and have that reported to MMW. It looks like there’s no code for calculated variables in the DRWI_CitSci.ino, but it is in the menu_a_la_carte.ino. Hope this helps!

Dave Bressler suggested I contact you for my issues noted above.

Thanks

Hi Sara @srgdamiano

I think I have gone as far as I am able on my Low Cost EC sensor project.  I added #include <sensors/ExternalVoltage.h> to the DRWI_CitSci code and registered GMI_test site using new ExternalVoltage_Volt(&extvolt) from the Sensorex RTD votage divider as a proxy for temperature.  I need to apply a simple linear correction (…[Read more]

Great! Thank you for taking the time to help me with this and trying to update the library.

No problem!  The wonder of git is that I actually could track back pretty quickly how long it had been since any changes were made and what those were.

I’ve pushed what I think should fix the testing mode to the develop branch of the ModularSensors library, but I haven’t actually tested it myself yet.

I’ll see if I can get it tested tomorrow and then pushed to the master branch.

Working on it right now for you.  It will be a library update.  The lack of modem update in sensor testing mode was an oversight; I want it to be there automatically.

I think I’m following. So how do I go about fixing that?

You didn’t manage to connect to the internet for the clock sync.  I’m not sure why that happened.

The modem values won’t update in sensor testing mode and they’re always updated at the *prior* internet connection.  Since you didn’t connect successfully for the clock sync, they didn’t update.

Hi Sara,

Thanks so much for your help. Making those changes to the code you last mentioned worked and it compiled successfully! I was able to upload to the board and that feels like a huge step. Thank you! I’m now monitoring the output from the board on VScode and everything seems to be in order except for the sim card. You can see in the…[Read more]

Thanks Jim.

In my case (manual upload), it looks like some of this might have been avoided by not uploading data out of order? Though that would probably not be possible for sites that transmit the data via cellular.

I had the same problem trying to fill in gaps for SL150 when the modem wasn’t connecting.  See the following issue https://github.com/ODM2/ODM2DataSharingPortal/issues/430

I think its a know problem that is on the ToDo list.
