@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]

Hi Scott-
I was able to get my LowCostEC sensor station uploading to MonMW using the AtlasScientific library.  However what I really need is a <LowCostEC.h> library file that will address the Atlas EZO circuit in UART mode, read and calculate temperature, and apply correction coefficients.  I looked at the  AtlasScientificEC.h code and its way ab…[Read more]

Thanks Sara for all the info.  Glad to get a yes on my last two questions.  Now I can go ahead and active my SIM cards with Hologram.

I added #include <Arduino.h> and still won’t build.  Can’t find SD.h which is in the adafruit library which I installed in my Arduino IDE  I download this program to my EC sensor station to set up the EZO board to calibrate the probe, RTD, and set the update rate of the AtlasEZO.  The easiest thing to do is to use the Arduino IDE when I need th…[Read more]

I uploaded DRWI_CitSci to my Mayfly board but I haven’t got to modifying this to work with my Atlas EZO sensors. I set up another project folder to load my Atlas setup code that I have been using for a while using Arduino IDE.

I am getting “…No such file or directory” error when I try to compile.  If I point the .ini to the logging to MMW it…[Read more]

Following the steps in episode 9 I right clicked on the simple_loging folder in https://github.com/EnviroDIY/ModularSensors/tree/master/examples

there was no option to copy the folder on;y a link to it.  How can I copy this folder and upload to my project which is local at …/documents/Arduino/GMI_ECx?
