  • No, I don’t think it could have been that long ago. I apologize if I led  you down an un-necessary rabbit hole – it very well could have been that the update to the library had no bearing on how the logging_to_MMW worked at all. It seemed to correlate, but I definitely have nothing definitive to point to.

  • Sara – Do you have any insight/help on why I (mostly) have success why using the logging_to_MMW program, which uses the logDataAndPublish command, but not with the double_logger program using the code you provided? It seems to print out the same information  in serial monitor of what it’s trying to do in both cases, but only returns on 201 on the…[Read more]

  • <p class=”user-nicename”>@srgdamiano – I wish I had looked prior to updating. It was at least July/August of 19, if not late February/early March of 19. I played around with using a back-dated version of the modular sensors library (by specifying the version in the .ini file) to see if I could figure it out.</p>

  • Sara and Jim, thanks for the replies! Sara, knowing where you are now without formal coding training give me to hope to continue persevering!

    Thanks for the code suggestions! The first – not creating new variables each time – worked great.

    The second, for uploading to MMW at first did not work, saying modemWake and updateModemMetadata was not…[Read more]

  • Hello – I’m attempting to take the double_logger.ino file and modify it for my needs – and would appreciate a little help. I’ve been logging pretty well to MMW with the basic logging_to_MMW.ino using a XB3-C-A2-Ut-001 with Hologram Sim card, primarily with a tipping bucket. What I’m hoping to do with the double logger is to log every 5 minutes…[Read more]

  • Hi Jim: I haven’t been following this thread but I’m excited that you are pushing through this to get your data streaming to MonitorMyWatershed! I’m glad Sara has been providing help. It occurred to me that you might reach out to Adam Gold (@adamgold) because he was using both Atlas Sci hardware and PlatformIO. He published a blog detailing his…[Read more]

  • Sara, that’s great, thanks for your response. You are correct – a primary reason I’m hoping to use a Mayfly with the Signature is the telemetry. The Isco modem, while I’m sure very nice, is prohibitively expensive and locks the user into going with telemetry the way they have it set up. I also like the ability of the Mayfly to interface with…[Read more]

  • I am interested in using the Mayfly to monitor the our water sampling stations. Basically, we have a flow monitor (Isco Signature) and an automatic water sampler (Isco 6712) to monitor water quality at a handful of sites. I am already using the Mayfly for basic weather monitoring, but am looking to expand to use it to also monitor a number of the…[Read more]

  • Need some guidance on how to install and maintain an EnviroDIY Mayfly Sensor Station? We’ve created new videos that will take you through the 10 steps of collecting quality water monitoring data. The following […]

  • Hi Oscamo. Indeed, I was formerly at Planktos Instruments but now at the Stroud Center. In responding to Sara’s comment about trajectory data being hard to visualize, check out this video showing dissolved oxygen data along 22 miles of the Neuse River in North Carolina.

    We’ve been collecting trajectory data with drifter technology here at the…[Read more]

  • Stroud Water Research Center, in conjunction with the OPEnS Lab at Oregon State University, is excited to host a DIY workshop this September.

    Overview:
    Low-cost, do-it-yourself electronic microcontrollers, […]

  • Sensors, no. Autonomous orthophosphate wet chemistry, yes. Check out Green Eyes Science’s NuLab (http://gescience.com/nulab/) and Seabird’s hydrocycle (https://www.seabird.com/hydrocycle-po/product?id=54721314201). There are others out there, but these come to mind first.

  • I’m connecting an ESP8266 V1.0 with a Mayfly. Can anyone suggest a simple sketch that scans for available wifi networks (and displaying them by printing to the terminal) and displays confirmation of the connection with my wifi by printing something to the terminal? Ultimately, I’d like to send sensor data to Monitor My Watershed, but the first…[Read more]

    • Well, the *easiest* way would be to take the ESP bee off the mayfly and connect it to a UartSBee and then talk to the bee directly using AT commands and a serial port.

      If you’d rather keep it attached to the Mayfly, you can use the basic example for the StreamDebugger (https://github.com/vshymanskyy/StreamDebugger) library to communicate with the…[Read more]

    • Um.. and it’s also possible that the esp I gave you had a botched firmware upgrade. If you’re not getting connected, come and demand a better one from me.

  • @adamgold Hey, Adam. I know you are exploring the Atlas Scientific sensor suite, so I want to connect you with Jim Moore (@w3asa) who has experience with the Atlas sensors. Perhaps one (or both) of you can submit a blog post with your application, hardware, and code?

  • A new manual is available that describes how to build, program, install, and maintain an EnviroDIY Mayfly Sensor Station. This manual is the result of years of experience our staff has gained in training over 500 […]

    • Wow. Thankyou Stroud Water team for detailed how-tos. Fantastic stream side setup for Mayfly, as well as good reference material for how to do water quality collection.
      One comment, is that we’ve seen sensor cables being gnawed. So we’ve tended to put the cables communicating to the sensors in a flexible PVC sheath. In the West we also get deeply incised channels, so have greater cable runs to get to a radio horizon.

    • Hi Neil, Good suggestion about “armoring” your cables. Others have done similar things in this region, including flexible steel electrical conduit.

    Has any one here worked on sending and receiving data from any SDI-12 based sensor using XBee RF radios? Please help with a sample sender and receiver code(Python if possible)

  • I have used the SDI-12 library with the decagon 5TM sensors without any issues, but tried the stevens hydra-probes and can’t get any values from the sensors. So my guess is the library doesn’t work with the hydra-probes, Please has any one worked with this sensors using the SDI-12 library?

  • Hello,

  • Hello,

    Has any one gotten to use the SDI-12 library with the Stevens hydra probe soil sensor? Please can you provide a sample sketch on how to communicate to this sensors and collect data from them?

    Thanks

  • Hello Hicks,

    Thanks for the reply, the sensors are buried completely in the soil as for the length i did not really measure that. Please see the attached file for the complete sketch running on the Arduino, and let me know what you think.

    /*This is the first code for taking data from the 5TM sensor and showing it on the Arduino serial mornitor…
