Sara Damiano replied to the topic Connect Arduino data logger and Arduino slave in the forum Other Data Loggers 1 years, 11 months ago
There’s an example of using an Arduino as an SDI-12 slave in the Arduino SDI-12 library.

Sara Damiano replied to the topic 0.33.0 release testing in the forum Mayfly Data Logger 2 years, 4 months ago
The a-la-carte example isn’t usable as written any more. It got to be too big so I filled it up ugly pre-processor conditionals and snippet markers to use for continuous integration and documentation.
There are virtual functions all over the library, which definitely are eating up memory. I think almost the entire inheritance chain for sensors,…[Read more]

Sara Damiano replied to the topic Hydros CTD-10 Regularly Dropping Out (-9999) in the forum Environmental Sensors 2 years, 6 months ago
If the communication works sporadically, it’s more likely to be an electrical issue than a code issue. Coding issues *usually* cause it to not work at all.
The -9999 is the library’s value for a failed reading. When you get in in SDI-12, it most often means the sensor didn’t respond or the response was garbled. Because the Mayfly’s voltage (a…[Read more]

Sara Damiano replied to the topic Problems with libraries on the Mayfly Data Logger in the forum Mayfly Data Logger 2 years, 6 months ago
The instructions for manual installation on the https://www.arduino.cc/en/Guide/Libraries are telling you how to find the right location to put the unzipped folder. Once you have the right folder, you cut and past the files. That’s it.
To update libraries, the easiest way is to delete everything in the library folder and re-download.
Can you c…[Read more]

Sara Damiano replied to the topic Pin locations for Yosemitech Y510-B in the forum Mayfly Data Logger 2 years, 8 months ago
Changing the address via the Yosemitech library is not hard. I would strongly recommend you do that rather than mess with two adapters and two serial lines. No matter what, I’m positive that the default addresses are not
0x04
or0x0B
as you have them coded. Those are just my favorite addresses for them.If you really want two separate co…[Read more]

Sara Damiano replied to the topic Pin locations for Yosemitech Y510-B in the forum Mayfly Data Logger 2 years, 8 months ago
There’s no enable pin broken out, so it must have automatic flow control. That’s what you want. This one, right: https://www.amazon.com/ALMOCN-Adapter-Module-Converter-Indicator/dp/B09998FY4X?th=1
You said:
Currently the RS485 wires connected to the Y510-B into the mayfly are as follows: GND to GND, RXD to D11, TXD to D8, and VCC to sv5.

Sara Damiano replied to the topic Connecting SIM7080 to New Thingspeak in the forum Mayfly Data Logger 2 years, 8 months ago
Sorry, I coded up the ThingSpeak publisher ages ago only to prove to myself that I could get an MQTT publisher working. I’ve never used it beyond that. I don’t have a paid account so after the trial period I was locked out and I’m not willing to do much testing on an account tied to my personal email.
Anyway, the code for ThingSpeak is in the…[Read more]

Sara Damiano replied to the topic Pin locations for Yosemitech Y510-B in the forum Mayfly Data Logger 2 years, 8 months ago
AltSoftSerial only works on pins 5 and 6. That’s why there’s no place in the code to declare the Tx and Rx pins. It’s strictly limited to those two.

<div dir=”auto”>Is there a reason you have the two sensors on separate RS485 adapters and power supplies? I’m fairly certain that the two sensors operate on the same supply…[Read more] -

It’s been a while since I’ve used Atom. Are you sure the program is compiling without errors and actually being uploaded? If there are errors in the build, it won’t actually be uploaded.

Done. Sorry for the delay. Let me know if you have any issues adding a sensor.

The conductivity probe was already there. I’m adding pH now.

Sara Damiano replied to the topic Modular Sensors wifi connection on university (or similar) network in the forum Miscellaneous 3 years, 2 months ago
I’m not sure if it’s possible – or if it is, it’s not going to be easy. When you log in with your phone or your computer, you go through a series of browser pages where you submit form data with your credentials, etc. I would guess that you’d have to manually figure out what the URL for each of those pages is and manually create each of the p…[Read more]

Sara Damiano replied to the topic Helium Network- Compatibility with Mayfly in the forum Mayfly Data Logger 3 years, 2 months ago
I haven’t looked into it much, but I would guess that module, and several other bee-shaped LoRaWAN modules would work just fine with the Mayfly. There is *not* any direct support for any sort of radio communication right now in ModularSensors. I would love to have support for it, but still a “someday” feature right now. Right now most of our st…[Read more]

Sara Damiano replied to the topic Testing power consumption in the forum Mayfly Data Logger 3 years, 5 months ago
I’d put it in the power up, since it’s supposed to happen right away and setting the pin is nearly instant and won’t slow down other things powering up.

I added 10 extra ms of wake time in v2.1.3. You can revert everything back to the original by adding a second argument of 0 to your send command functions.

Sara Damiano replied to the topic 504 Response Code in the forum Mayfly Data Logger 3 years, 5 months ago
Doh, yes, Shannon’s right! I didn’t look closely enough before I deleted it, but there probably is a missing UUID!
Looking back, I replaced all the UUID’s with <<REMOVED>> for you so because you probably don’t want those to be public. I can’t see or revert it to the original, but looking at it, your last measurement has just

Hmm. Does Hologram show any data being transferred?
Monitor My Watershed is known to sometimes drop or not respond for no apparent reason. But usually if one station is working all the time and another isn’t it’s either the UUID and tokens or the internet connection. When you’re looking at MonitorMW, are you seeing anything at all? The num…[Read more]

Sara Damiano replied to the topic 504 Response Code in the forum Mayfly Data Logger 3 years, 5 months ago
I should add that we haven’t figured out why some connect right away and others don’t. So even with an apparently identical batch of sims and modems, it wouldn’t surprise me if some connect immediately and others don’t.
I removed the UUID’s from your post.

Sara Damiano replied to the topic 504 Response Code in the forum Mayfly Data Logger 3 years, 5 months ago
Do you see any connections or activity from the SIM cards on Hologram? Sometimes it takes a really long time to connect to the network with a new SIM card, a new modem, or at a new location.
Are you sure your tokens and UUIDs are all correct?
