If you sensor is in water that is deep enough so that ice doesn’t form around the sensor itself then you should be ok.  If ice forms around a sensor itself that can be a problem.  The Meter Group Hydros21 CTD sensors have pressure transducers that can break if ice forms around the sensor.  The new model CTD seems to have a pressure transducer th…[Read more]

@shicks, has anyone from Stroud contacted Verizon about this? I am also hitting a wall with adding the LTEBee modem to our Verizon account. The rep from Verizon that we work with is willing to speak with the device manufacturer to get them added to the Device Management Database. How do the LTEBee modems differ from the Digi modems such that…[Read more]

Hi @shicks (and thanks @neilh20),

Thanks for that.  I am using a Yosemitech Y511-A with a Hydros CTD (Gen 1).  My code is fairly similar to yours.  I notice that you use pin 22 to power the Y511 (line 145) where I have ‘-1’.  I also don’t see the line ‘<span class=”crayon-i”>AltSoftSerial</span> <span cla…[Read more]

@mbarney, do you know if the REVX plan/sim card you had success with is the CATM version (50mb for $5) or the 4G version (10 mb for &12)? With the new modems I have not been able to register on the network (cereg 0,3) using the 4G plan and sim that worked for a couple years with the old xbee modem.

@shicks,  RevX systems technical support has…[Read more]

What was the solution to the problem? We are having trouble with our location dot still being gray. It is clearly collecting data but is not displaying the numbers below the graph under last observation . @shicks

@shicks.  I tested the converters you recommended and they appear to work as expected:

dropout voltage is 8 Volts and will support input voltage to 31.5 V (max on my bench PS).

No load draw is 3.64 mA at 12 V and 2.83 mA at 31.5 V.

A lower cost option is a three terminal non-isolated converter at $2.76 ea vs $12 for the PlusRoc.

Hi @shicks  I got my 5 pack of the v1.1 boards today and I noticed that:

• Removed External/Lipo slide switch since it’s no longer needed

Does that mean I can no longer power the Mayfly from a 12 V supply?  I have an application for water sampling and the pumps run on 12V and they are controlled by the Mayfly so I can power the whole system wit…[Read more]

@jlemontu-org, yes as @shicks pointed out you or your colleague can follow up on this on ODM2DataSharingPortal Github issues page.

This is a known issue and I did already post to github about it, but if you want to add more info you can go to that post:  https://github.com/ODM2/ODM2DataSharingPortal/issues/551

@shicks, thanks for your help anyway Shannon.  @aufdenkampe, any insight on the code above would be greatly appreciated.

@neilh20, yes all setups are the same.  Some work fine, others have issues with dropping out.  I have spare Mayflies and a spare CTD, but no spare turbidity sensor.  Did you ever end up producing your Mayfly wings for the 0.5…[Read more]

Hi @shicks.  I’m just wondering if you saw anything in the code above that might be causing this problem?

Regards,

James

Hi @shicks and @neilh20

I’m leaning more towards an interaction with the MODBUS wing.  I had one station that produced -9999’s constantly when the Turbidity sensor was plugged in, and operated fine when I removed the MODBUS wing.  This drove me nuts until Anthony pointed me towards the complex loop code where I set the Turbidity sensor to low a…[Read more]

@shicks

I emailed the sketch and the associate pio .ini file.

Thanks for looking into this.

@shicks just wondering if the RS485 schematic is likely to be published, and of course if the parts are likely to be available. Many thanks.

After probing the screw term adapter, I don’t think that it will work for my purposes as I described above. If I’m correct, the way the adapter’s voltage divider works is this: When the S1 jumper is set to Res-Div and two matched resistors are installed on the S1 side of the adapter, the voltage output on the Grove’s D1 pin will be half of the…[Read more]

@neilh20 @shicks @vogelrnws

Hi all! Thank you for all of your feedback and tips! I spent some time this week looking at the mqtt3.thingspeak.com server and I was able to get a channel up and running on it.

Overall, it’s not drastically different than mqtt.thingspeak.com. The main aspect being removed in the legacy Thingspeak server is the API…[Read more]
