Hi Neil

I had a go at arduino cloud about a year ago.

For price/configurability I ended up switching to Blynk. I’ve had 5 arduino MKR GSM boards function flawlessly for the past year. I think Blynk is aimed at developers, but there was enough sample code for me to get the board running .

That said, the current arduino pricing looks good.

I’ve…[Read more]

@w3asa Glad to hear you were able to download your data. The Monitor My Watershed download function may not perform well if the file size is too large. Here are a couple of tips for avoiding download timeouts:

• Don’t collect data at 5-minute intervals for long periods unless you know you need it for a particular parameter and site; 15-minute…

Never mind!  “download Sensor data”  seems to be working now.

“download Sensor data” was very slow to respond (several hours) now it doesn’t seem to work at all.  Does anyone know the status of this? Is there another portal to download station data?

Thanks Shannon!

That’s a good question, and something that I’m sure a few other people have accidentally done before, me included.  Luckily the charger chip and the Mayfly v1.0 and v1.1 board should not be affected by having a solar panel connected with the wires reversed.  I just did a test here with a Mayfly v1.0 and a v1.1, where I first connected a panel w…[Read more]

Thank you for your advice. I changed the I2C address at line 34 in the AOSongAM2315.cpp. I got this output ..

Hi!
I have quite the same projects ! But still wondering wich is the best solutions.
I had good results with MaxBotix products, but they are limited to 15 meters max. So it’s seems a better option for surface water than underground water.
What have you chosen finaly ?

Thank you, Scott. I am not used to this forum and got a bit mixed up.

@rhouck, @damiano moved this post to a new thread here. I noticed that you reposted to a different thread. Please reply to this thread.

I know nothing about rosserial. Are you using Hardware Serial with it? Serial or Serial1? Are you using some type of software serial (SoftwareSerial, AltSoftSerial, NeoSWSerial)? Very quickly skimming the rosserial docs and code, it looks like it has some specific boards that are supported and the 1284p in the Mayfly may not be 100%…[Read more]

Hello, my senior project team at Lake Superior State University is using the Mayfly board with the Hydros 21 CTD sensor.

We are using the ModularSensors library and we’re wondering if there is a power cycle taking place that could affect any serial communication. There are no issues with communication or connection when sending data from the…[Read more]

I’m not familiar with the new C model, but I did use the older, now-discontinued one awhile back.  Without digging into the manual and the library too deep, I’m guessing it might be an I2C address issue?  The old model used 0xB8 whereas the new one uses 0x38.  So go into the ModularSensors/src/sensors folder and edit AOSongAM2315.cpp, find line 34…[Read more]
