Scott Ensign replied to the topic Not able to download readings in the forum Monitor My Watershed 1 year, 1 month ago
Neil, there is a faster and more flexible way to extract data from Monitor My Watershed. Instead of using the CSV download button, try using either python or R to extract specific time periods of data for specific sensors and stations. Sara has documented these methods here: python version and R version.

Dear Mike, congratulation for this nice development! I understand from your description that you focus on adults, but I didn’t clearly understand if the device is set underwater or close to stream to focus insects […]

Kurt@UR started the topic Inexpensive DO probe recommendations in the forum Environmental Sensors 1 year, 1 month ago
Hi Water Quality fans,
I would like to hear people’s experience with inexpensive dissolved oxygen (DO) probes, especially over long periods of time left in a river and if there are recommendations on what probes to use. The desire is to keep the probe in a river 24/7. The application is in an urban environment somewhat hidden but still near…[Read more]

I got it to work.
I edited the libraries and logging program to use the new sensor. https://github.com/brianjastram/GHWX/tree/main/GHWX4

I’m just wondering if anybody is seeing a problem with download readings. I’m not able to download readings – its timing out after 5minutes -sometimes it seems to work but its not clear why.

I realize there are some nifty ways of compressing data – and it may not all be quickly…[Read more]

Wow! Thank you again.
I am so impressed by your detailed, expert, and helpful response.

Mayfly v1.0RevA had a Max17250 boost chip that used the following resistors in order to set the output voltage at 12 volts:
R15 = 10k
R19 = 84.5k
R31 = 220k
When it was time to manufacture more boards in 2021, there was a semiconductor shortage that made it impossible to find that particular boot converter, so the design was modified to use a…[Read more]

Thank you so much!
So just to be clear, there was no design change in the 12V boost from v1.1 Rev A to v1.1 Rev B, just a correction in the resistor used during manufacture? Were any other aspects of the design changed at this time?
If so, maybe it would be helpful to add some Rev B documentation to the “Changes” list shown on this page: https:/…[Read more]
Shannon Hicks replied to the topic Why is 12V power on Mayfly V1.1 (rev A) nominally only 11.3V? in the forum Mayfly Data Logger 1 year, 1 month ago
In 2021, there was one small production run of the Mayfly v1.1 RevA boards that, due to an error by the manufacturer, used an incorrect resistor value for the 12-volt boost circuit, resulting in a lower output voltage, around 11.3v. This was corrected in the next manufacturing run, along with making a few other changes, which is why the v1.1…[Read more]
