I tried just DS18Temp but that didn’t work.
The Celsius temperature from the DS18 is a reasonable 22.25 degrees.

Now I got it to be 33.8 F by replacing
float TempF = TempCFromMaxiumDS18_Temp*1.8+32 with
float TempF = true*1.8+32

Awesome, thank you. That solved the error. I was wondering about my variable array because I saw the format of the variable array in the baro_rho_correction sketch and it was more bare bones.
Now I’m puzzling on the -17966.20 Degree F output I’m seeing in the serial monitor. I tried adding true to the ds18->getValue(true) but that didn’t work.

Maybe one of these would work.

Shannon, great job moving the science forward. It seems like your line of experimentation could lead to a simpler way to count rain gauge tips and transmit the data to MMW possibly without using a ProTrinket. Maybe if a tip happens while a cellular transmission is happening the transmission could be interrupted, the tip could be counted, and then during the next send interval the data could then be sent to MMW. I am looking for a way to reliably count every tip and send all tip data to MMW even if a send interval is missed here or there.

Using @aufdenkampe ‘s advice as a clue I replaced the 25′ of extra, coiled, shielded analogue signal cable from the original installation between the rain gauge and the ProTrinked with a 3’ length of shielded analogue signal cable on 11/6/2020 and haven’t had any false tips since.

Thank you everyone for the input.

Best Regards,

Brian

scornia,

I was having the same problem with the address change sketch (using the Atom PlatforIO) so I tried using Arduino IDE and that worked. It saw the SDI-12 address of 0 at pin 7 and I successfully changed it to 1 and now I’m getting values from the Meter CTD-10. Good luck. Let me know if you have any questions.

[BrianJastram]

Sara, Thank you (sigh of relief of knowing why it wouldn’t work). That was my goal and now I know it shouldn’t be. That is very helpful. No wonder I couldn’t find an example anywhere.

Shannon, can you share your code for enabling the Mayfly to keep track of the cumulative total?

[BrianJastram]

I don’t know how to do that but I think I could figure it out. Can you point me in the right direction?
Best Regards

I checked the SD card from one of my cellular enabled Mayflys and was surprised to find 14 .csvs created in the last 20 days. Some of the breaks (with missing data point) in the .csvs match with a missing data point on MMW. One of the gaps on MMW is between voltage values of differing digits after the decimal, 4.745 and 4.73. So now I’m seeing missing data points in between consecutive .csvs on my SD card and missing data on MMW that is recorded on my SD card. I’ll work on the deep debugging and clarify my situation. Right now I don’t have a good questions to ask.
