I am using the same hardware with my Low Cost EC stations   which is set up for UART mode but I have since upgraded to I2C mode when I added the 2G modems.  I am using the sensorex probe for the EZO EC which has an integral RTD which I read thru the analog input.  I think its only about a $30 premium for the the RTD option.  Maybe there are som…[Read more]

Thanks for the info Shannon.  I will check out the GPRSbee and sd card to see if they are the cause of the 2.4 mA draw when in sleep mode.  I’ll try a new Mayfly board next.

@shicks

I checked my GMI_EC5 station that I mentioned above that was not keeping up and I measured about 2.4 mA current draw when the mayfly is in sleep mode.  I thought it should be close to zero when in sleep mode.

Any thoughts Shannon?

@mbarney

I have the same issue.  I have my LEC stations (GMI_ECxx) running with 2G cell service and I did have one station that the solar charge chip failed and caused battery to drop below the 3.55  volt threshold for upload.  However GMI_EC5 seems to be getting a charge during the day but is still not keeping up.  I attached a screen from MMW…[Read more]

I checked Amazon and finally discovered that “envirodiy mayfly protoshield” works for a search.  Did not have envirodiy in my search query.

I just bought the last one so guess time to restock

I just checked Amazon and no Protoshields showing.  I guess shipment processing isn’t one day turnaround!

Any updates on the availability of the Protosheilds?

Thanks.  I am using the FTDI port and wiggled some plugs, etc and now is loading ok.  I assume when I was getting that error the mayfly was plugged in and turned on because when I attempt to load with the pwr switch turned off I get the following e…[Read more]

Hi Sara @srgdamiano

I haven’t used PIO for several months but in preparation for the transition from 2G to 4G I launched PIO this week and it apparently did an upgrade and now my code won’t load.

I get the following error:

avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00

PIO is currently core 4.3.4 and home 3.2.3

@heather

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]

@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]
