neilh20 replied to the topic Battery Capacity /Fuel Gauge in the forum Mayfly Data Logger 1 years, 1 months ago
An update – I’ve found I2C bugs in some of the ST3100’s devices – that I couldn’t get a work around. It may be to do with the AVR I2C master. Some other engineers are using it with an STM32 / ARM system that they aren’t seeing the same problem https://github.com/neilh10/STC3100arduino/issues/1
From using the STC3100 -…[Read more]

@jp thanks for sharing – power is a challenge when there isn’t enough of it. Finding enough power for your systems is the easiest step, – that is upsizing the solar panels, and ensuring they have enough solar aspect this time of year.
Just wondering, what is the standard kit that you have and source- sounds like you have the Mayfly 1.1 – what…[Read more]
James P replied to the topic Monitoring power consumption in the forum Mayfly Data Logger 1 years, 1 months ago
We have the standard Mayfly kit from TU…the sun here in the winter is apparently never strong enough to charge the battery with the default solar panel and battery. The voltage reading may get to above 4V for a short time (maybe 1 hr per day), but quickly drops and no more data is transmitted. I dont know if the voltage i see is coming from…[Read more]

I was wondering if anybody is interested in exploring this topic. How to create a low cost bubbler depth gage.?
I find my inspiration comes from seeing a few unrelated new parts and thinking what if these where put together – could that be a low cost bubbler.?
The inspiration in this case was seeing that Adafruit has a low cost 15psi air pump,…[Read more]

Have you had any luck getting it to work? If not, have you tried opening the Arduino Serial Monitor to see what the Mayfly prints to your computer when the Mayfly starts up and after each attempted sensor reading? You can also email your sketch to me at mayfly@envirodiy.edu if you’d like me to take a look at it to see if it’s possibly a code issue.
Shannon Hicks replied to the topic XBee RF / Mayfly Communication Troubleshooting in the forum Mayfly Data Logger 1 years, 1 months ago
It’s been a while since we’ve used Xbee modules with our Mayfly boards, so I don’t remember all the tricks to configuring the routers and coordinators, but your Mayfly code looks correct to me. Have you tried removing the wake and sleep commands and just leave the Xbee module constantly powered to see if that helps? Are you using the Mayfly v…[Read more]

Hi,
A bit frustrating, as this was working last week, but something (hardware or software) seems to have happened. Regrettably, I do not have git VCS in place for my workflow on this, so can’t say exactly what is was that worked before. But it wasn’t overly complicated or much different from anything I’m trying now.
The basic setup is a M…[Read more]

Also, it looks to me like the cellular Bee hasn’t turned on in about a week. I checked my hologram account and it confirmed that it hasn’t been turning on.

I took your suggestion and went in and changed the channel, it was already on 1 so I just changed it to 2. I tried setting it back up however now Monitor my watershed is not receiving anything and the red suspected power out light on the bottom left of the board is on. I am quite lost on what to do, any suggestion would be greatly appreciated
