@shicks I agree it would be good to see the software. For my systems I look to have it last 14days before it reaches 3.8V and it is a difficult target unless its being tested for and the time taken on the radio is also characterized.
I see the issue is how to keep the sensor readings delivered reliably while there is enough power, and then when…[Read more]

Hi @shicks, just received two Mayfly 1.1 and noticed they are rev1.1B – just wondering what the differences are from rev1.1A? 🙂
I did pull the circuit diagram from https://www.envirodiy.org/mayfly/hardware/ however the resolution is so low, its not all readable. Just wondering if there is a pdf version. 🙂
I also checked…[Read more]

Braedon replied to the topic How to determine battery and power supply in the forum Mayfly Data Logger 3 months ago
Awesome. The XBee module is an RF module, the XBee Pro S3B. I just remembered, while the apogee sensors I am using don’t require power to make measurements, they do require power for the internal heater. The pyrgeometer heaters, according to the datasheet, draw 15.4 mA and 185 mW at 12 VDC. The pyranometers draw 30.8 mA and 370s mW at 12 VDC. In…[Read more]

Sedhead started the topic Mayfly sketch compiles, seems to upload, but doesn't in the forum Mayfly Data Logger 4 months ago
I am using VSCode and Platformio to upload sketches to my Mayfly boards. The sketches compiled and uploaded fine two weeks ago. Today, when I went to deploy the sensors, the code compiled fine and it even looked like it uploaded fine, except that the upload was way too fast. Usually there is a bit of a lag as the code is being written to the…[Read more]

Sedhead started the topic Get MMW data in real time? in the forum Monitor My Watershed 5 months, 1 week ago
Is it possible to get data from an MMW sensor in real time from the website, not by downloading the data as a .csv? I’m looking for a way to grab data from some sensors and then plot them on a custom web app for our university.
Thanks!

I think I found the answer by emailing support@rexV, since I got it from amazon.com Mar.2022 it wasn’t certified for Verizon.
This can be checked https://opendevelopment.verizonwireless.com/activation-troubleshooting

Hi Shannon (@shicks),
Thanks for your reply, and apologies for not replying sooner. My replies to your message are in bold:

Hi @shicks and @srgdamiano. You’re not going to believe it but the addition of the build flag below has fixed my problem, at least for the Gen2 sensors.
-D MS_SDI12_NON_CONCURRENT
I am certain it is this build flag and not the voltage pin (previously set to 5v) because I uploaded my script prior to switching the voltage pin over and it su…[Read more]

@shicks, would you mind publishing your Y-511a + Gen 2 Hydros21 CTD code so I can ensure I haven’t done anything wrong on that front?
Thanks in advance.
James

Hi everyone,
This problem has been causing me trouble for nearly a year, but it has become unworkable with installation of Gen2 Meter CTD sensors.
My problem: Meter CTD (SDI12) and Yosemitech 511-a Turbidity (MODBUS) sensors seem to interfere with each other causing the CTD to sporadically drop out return -9999 values. This only occurred at some…[Read more]

Dave Bressler replied to the topic MayFly Data Logger During Winter in the forum Monitor My Watershed 10 months, 2 weeks ago
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.

Jim Moore replied to the topic Mayfly v1.1 technical questions forum thread in the forum Mayfly Data Logger 1 year, 8 months ago
@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
