Thank you so much Shannon!

One very minor last question – for the DIP switch, that would be turning the USB DIP to ‘off’ for the purposes of LED operation, correct? The ‘Power’ DIP switch would remain ‘on’?

Thank you!

Dave

Shannon,

I ordered several boards in the 1.0 release in the fall as replacements for 0.5 boards that are currently in the field. Our setup for those involved using DIN rails to connect large marine cycle batteries so we could keep our terrestrial stations operational during the winter. So, we used the 12v regulator on the 0.5 board and it has…[Read more]

Shannon,

We had been using the EnviroDIY Libraries as well as libraries contained within the IDE itself. Our code uses sections of the sample logger sketch, but have been built out a bit to combine possible analog sensors as well as communicate with Xbee.

I’d be happy to share with you – it’s not super long and you’ll see that it is pretty…[Read more]

A small update for everyone:

We were able to allow the Mayfly to operate by updating the libraries in our code. We are using some core IDE libraries as well as some EnviroDIY libraries. My sense is that there might be a conflict between the recent update to the SD library, and perhaps a pin interrupt library from EnviroDIY, but I’m not sure.

One…[Read more]

That’s a good thought – the only thing is that we have the identical setup nearby that we installed in November with the exact same battery and solar panel, and those function with no problem. We don’t believe there is a difference in the physical infrastructure that we can tell – so the only difference could be what libraries we installed?

Hi everyone,

Some updates on this project – we now have 12 loggers monitoring 8 sensors at each site. It took a full field season but now have all the wiring free of shorts and power problems. We have mostly been focused on the data collection side and, because of COVID, don’t have resources to work solely on the 900Mhz radio network element…[Read more]

Wow! That is amazing – and very helpful! I thought it may be an issue with a line in the library – we migrated to Meter group sensors which seemed to work – perhaps because of their ability to wake up more quickly.

Thanks for the update Shannon – we have 12 out in the field for collecting soil moisture in a project with the USFS – I should probably update that thread. We are looking to buy 15 more for installation in Vermont now, too.

One cool piece of info for you all is that the Mayflys we had installed over-winter in northern NH made it through -20F…[Read more]

Greg,

We never revisited the issue and instead just gave the address to the CS-215 via a CS logger. I know that our team installed an ATMOS-14 at the site, and got around power issues by just powering the sensors separately from the Mayfly board by using DIN rails. It really seems that the different power requirements between the board and the…[Read more]

Hi everyone,

Very quick question. Something I didn’t see listed in the above replies has to do with antenna selection. Anthony or Sara, do you have a recommendation as to an antenna for one of the new Digi LTE-M Xbee3’s? We have had really good success with the 900mhz xbees and are now working on projects where there is cell service, so we’re…[Read more]

Shannon,

This is very helpful! We’ve ordered a few XBee PRO S3B 900 modules but are having trouble getting them to communicate via the Mayfly script.

One thing we think may be a problem is whether or not we chose the ‘programmable’ version of the modules. I noticed that Scott had an issue with this in another post from earlier in the Spring, and…[Read more]

Hi everyone,

Just an update here. Due to the issues with the CS-215, we ultimately decided to go with the Meter Group’s ATMOS-41. It worked seamlessly with the Mayfly and our script and we had no issues with addresses or voltages. Seeing that it was relatively similar in cost, it was an easy decision. This evades the answer to the question, so…[Read more]

Sara,

Just to loop back – we were in touch with Campbell and their suggestion was also along the lines of the 3.5V voltage requirement. In the meantime, we picked up a Meter Group (formerly Decagon) ATMOS-14 sensor which collects temp/RH/VP and it worked perfectly. Since we only had to install one, we just went with that.

We’ll try to figure…[Read more]

Hi Sara,

We spent several hours today trying to work with the CS-215. We did update and use the most recent library (1.3.1) but were still having issues with the two examples. For the address change example, all of the addresses were vacant, even though we had defined the sensor having an address previously using a CR1000 (Campbell) logger. The…[Read more]

Hi Sara,

Thank you for getting back to me. I’ll check the version of the library we have and will capture the serial output. We won’t be having a lab meeting until Tuesday so I will send it right after that. I noticed that there were updates last month so perhaps that will sort things out. In the meantime, thank you for helping!
