I’m looking to access Mayfly data from MonitorMW.org for the development of a simple web application to display the current reading of a variable. If there exists a CORS friendly access method for MMW station site data, please let me know.
Shannon, great job moving the science forward. It seems like your line of experimentation could lead to a simpler way to count rain gauge tips and transmit the data to MMW possibly without using a ProTrinket. Maybe if a tip happens while a cellular transmission is happening the transmission could be interrupted, the tip could be counted, and then…[Read more]
I’m guessing you’ve made one of these: https://github.com/EnviroDIY/TippingBucketRainCounter
I’ve edited the code that makes it work with ModularSensors, but I haven’t ever built one. Sorry.
I’ve got 5 solar powered Mayflys deployed with ProTrinket tip counters connected to heated and non heated rain gauges reporting their data to MMW via Digi XBee3 – RF TXRX Cell 4G LTE AT&T Verison – XB3-C-A2-UT-001 modems. These deployments range in length from 2-14 months. Within the past few months two of these setups have started reporting tips…[Read more]
Has anyone purchased Yosemitech sensors recently? If so, from where? I’m hoping there may be a US source, as I’ve heard it’s tough to get them at the moment because they’re subject to export tariffs. @aufdenkampe?
Great news, @aufdenkampe! Thanks to you and your team.
I ran a test overnight, with a Mayfly sampling every 5 minutes. Out of 179 samples sent to MMW, only one received Response Code 504, at 04:30 MST, Aug 7th. All other POST messages received successful response codes (201). The 04:30 point did not get saved to the MMW database. What I’ve…[Read more]
Matt Barney started the topic Add Sensor button not working on MonitorMyWatershed in the forum Mayfly Data Logger 10 months ago
The “Add New Sensor” button does not respond, as of 08:55 MDT.
Is this something you can help with, @aufdenkampe?
@aufdenkampe, I’m sure that the Tagolas did better when it was new. You can’t really tell in my picture, but all of my bigger antennas are sort-of crumpled from being dragged back and forth in my backpack and getting shuffled around on my desk.
Most cellular antennas are very wide band or ultra wide band – they cover a lot of frequencies. An…[Read more]
@aufdenkampe – any thoughts?
Postman automatically tacks on more standard http headers than I include in the post from ModularSensors. I wonder if one of them is making a difference. In PostMan after making a request you can click the “Headers” tab and you’ll see 8 or 9 “temporary” headers that it used in addition to your token header. M…[Read more]
Hardware-wise, do you have an antenna attached to the “cellular” uFL connector? You’ll never connect without an antenna.
But.. these LTE boards are just more finicky than 2G, so…
You’re using the example from ModularSensors, right? https://github.com/EnviroDIY/ModularSensors/tree/master/examples/logging_to_MMW That example should work with…[Read more]
Those settings should be right for the XBee Wifi. Are you sure the unit is connected properly to your wifi? Can you connect the unit to XCTU and try to send a test json in the console log of XCTU?
That example sketch should still work, but for anything new I would recommend you switch to using the ModularSensors library to send data to the…[Read more]
Hopefully @aufdenkampe will confirm but I think he went the USB route mainly to avoid power losses in the step down. If you go that way you probably need a relatively expensive 12V to USB to make sure you are getting less loss than the built in step down.
Depending on the version of the Mayfly you have, there’s a 12V power input that you can step down and use. If I remember correctly, though, @aufdenkampe once told me he’d had smoother power and less loss using a separate 12V to USB step down and powering the Mayfly via the USB port.
Unfortunately, though, with either option you would still need…[Read more]
We (mostly me and @aufdenkampe, I think) have been purchasing them directly from Yosemitech because they are so darn cost-effective without compromising quality. Currently they are subject to the new 25% “Trump Tariff,” but they are still proving to be cost effective. Note that to use these sensors, the Mayfly needs a “wing” to boost…[Read more]
I’m running into a low power issue with the sensors/RS485 turned off.
There is a backfeed going on, which leaves SW_3.3V at about 2V and LED3 comes on.
I think @aufdenkampe gave me a hint of this and described a solution
https://github.com/EnviroDIY/ModularSensors/issues/140 in discussion with @srgdamiano
However I can’t find it in the…[Read more]
I spent the day outside yesterday, adding more sensors to two existing stations, which included some RS485 sensors. I’ll share how I did it and that will hopefully help you along!
The stations are: https://data.envirodiy.org/sites/WSP01/ and
My sensor station added RS485 sensors and a new…[Read more]
Hi, I’m a newbie to Mayfly and looking for any hints on setting up an environment.
I’m planning the software on how to do a low power RS485 with logging/SD and sending to the internet (wifi then …) … solar powered of course … which means low power needs to be builtin from the start.
I’ve got my RS485wing board and proven the Pololu +12V b…[Read more]
many thanks for the pointers and for @aufdenkampe system level parts.
I haven’t used the Mayfly before though I got Mayfly 0.4 and chatted with Shannon when she was in San Francisco.
I’m building a test capability for interfacing to Keller Nanolevel depth sensor – RS485/Wingboard/Mayfly 0.5b.
If I can juggle it, and pull together a…[Read more]
Also, @aufdenkampe has a list of the components he has compiled for his work group. It’s informal not a bill of materials, but it may help you along (it has definitely helped me): https://docs.google.com/spreadsheets/d/1x87AHmmCWmsgMVpbeEhw9iZm5iHPiUoJPuaUpzHsxW0/edit?usp=sharing
Do I understand correctly that you haven’t used a Mayfly for your…[Read more]
Great to hear you are doing a power shield with capability to deliver to the EnviroDIY water quality data portal.
There hasn’t been a hw solution yet that I liked, that so I haven’t done anything with the Arduino libs. Maybe that will change.:)
I’m planning on doing a poster at…[Read more]
