These were just deployed 3 days ago and have been doing this from the beginning.

I am curious, did this just start or when you look back on battery voltage has it been doing this foe a while ? TomG2

We have 2 stations we’ve recently deployed which are reporting ~7.5 volts during the day and 4.2V at night (graphs attached).
I suspect that the solar cable was accidentally plugged into one of the LIPO BATT ports (with the battery is plugged into the other LIPO BATT port). They’ll get that corrected asap, but I want to ask @shicks: Would this…[Read more]

My USB connect to a rev1.1 board appears to be failing.
It was working, and now its stop connecting to the PC, stops even causing an audible ding.
If I take the same USB C cable and plug it in to the USB C of a Rev1.0A3 it sometimes works. Usually causes an audible ding, but sometimes doesn’t appear as a com port.
I’ve rebooted my PC twice, and…[Read more]

One aspect of measurements the Mayfly does manage is the time. If the small battery gets used up, then it will reset to a default time. Another way of checking time is roughly accurate (+/ couple hours) is when the peak temperature occurs.

The CTD does not allow an internal calibration, but we do a calibration in the lab with conductivity standards and apply the calibrated data as a calculated variable.
This is maybe semantics, but the Mayfly wouldn’t be a source of quality (or the lack thereof). That’s the sensor’s job. CTDs are usually pretty durable.

Hi,
Our Mayfly 0.5b has been redeployed after sitting in storage for more than a year. Yesterday I downloaded a week’s worth of data and I’m wondering how to tell if it is accurate and that the CTD probes are working as they should.
From a quick scan of the data I’ve noticed a few things.
