Hi @jp – I only install 2.5W or for a shady location I upgrade to 10W. Can you share the site that is publishing on, and can see how fast the power went down.
The non recharge batteries could work – but you need to do a lot more power calculations to understand how long they will work. 4 batteries (4*1.6V =6V) will work for a boost plugged in…[Read more]

I think it’s reasonable to pay for the hosting of these data, and the price structure allows small organizations to afford a few loggers. Are you planning to allow or make it easier for subscribers to use their data in real time on their website (via either iframe or another method?). This would allow us to more easily fundraise (for ex…[Read more]

What version of Mayfly board do you have? And what brand of cellular board? There are a lot of combinations of hardware on EnviroDIY stations, and some are much more efficient than others. Also, do you have a spare Lipo battery that you can fully charge separately in your office and then put it into the station? If your logger is only wor…[Read more]

Hi thanks for responding. I’m sure our system is undersized for our location. Today was a pure sunny day, last week we installed an extension pole and cable so the solar is up plenty high to get direct sun. But today we got no readings sent via cellular.
Our battery is a LiPO 4400mAH 3.7V.
The solar panel is a 1W 6V
Open Circuit Voltage:…[Read more]

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 11 months, 1 weeks 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]
neilh20 started the topic Low cost bubbler in the forum Environmental Sensors 11 months, 2 weeks ago
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.
