Since it’s not a MMW issue should I move my technical questions back to my original post on “infrastructure and equipment” forum?

Thanks for the update, Shannon.  Are there any plans to buy a quantity of 4G hardware in the expectation of a discount?  I will need at least 8 and would be glad to help out where needed.

I reposted this here from my post this morning on “infrastructure and equipment” forum:

“I noticed that what appears to be a general shutdown of the 2G network in the N. Chester county area which occurred Sunday, 7/12, at 13:45 EDT.  I have 8 stations in the Great Marsh Institutes’s network.  Three of these woke up this morning but the othe…[Read more]

Amazon says the protoshield is unavailable.  Are there any plans to restock?  I need 2-3 protoshields.

@chuckkir

Thanks Chuck for getting my Sensorex RTD voltage divider output converted to °C.  I plan to leave the EC as the raw value from the AtlasScientific EZO circuit.  Attached is the code addition to DRWI_CitSci.ino to get the Sensorex probe data published to MonMW:

Sorry forgot to add the links: GMI_test and GMI_EC1.  The other sites GMI_ECx are currently manual upload.

Thanks Chuck for offering to help with my coding issues.  I have two sets of code that I am currently testing with my Low Cost Sensor Station.  Simple_logging.ino is working on my mayfly platform which I am using to test the compensation routines to convert the raw data from the AtlasScientific EC sensor a…[Read more]

I am currently working on setting up an array of Low Cost EC sensor Stations in Great Marsh, N. Chester County to monitor UNTs flowing into this large wetland.  My current issues are compensating the raw sensor data to µS and ºC.  See my forum thread.

I currently have six stations and will probably add more all using the the same operating cod…[Read more]

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]

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]

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.

I seem to have “detached” my screen shot

@srgdamiano I decided to go back to basics with ModularSensors – getting started but took a while to get PCsync to load.  See attached screenshot with the corrections I had to make on the src_dir.

What is the function of the .pio folder and is it automatically populated when creating a new project?  I had to manually load the .pio/mayfly folder f…[Read more]

I noticed a similar issue regarding response codes when I first got my project uploading to MonMW.

Copy of my response on another forum thread:

Couple of questions:
I noticed several different response codes from the server – 20x(good) 40x(eror). Yet the data uploaded successfully in both cases. Are these related to signal strength or slow r…[Read more]

I don’t understand all the details but I get your point and no need to worry about baud rate!  I can change the pin connections on my proto-shields to the SDA and SCL pins, no problem.  However calculating temperature from the RTD on the Sensorex probe and correcting the EC reading of the Atlas EZO will be a challenge for me.

I posted more d…[Read more]

@stoltzfus-12osu-edu/ I am in a similar situation with my low cost EC sensor station project.  I need to tweek the AtlasScientific sensor library to fit my hardware.  I am using an AtlasSci EZO circuit set for UART mode and a sensorex conductivity probe with internal RTD which I use to report temperature as well as correct the EC reading to 2…[Read more]
