Since I am only using one C-FLOUR sensor, does having two pair of soldered resistors affect anything or should I redo the screw terminal board to only have one pair of resistors?
Thank you for the tip on needing two separate screw terminal boards because each C-FLOUR needing 2 ground terminals each.

If you only have one C-FLUOR sensor, then you only need one pair of resistors, since there’s only one analog signal from the sensor. There ARE two ground wires, which is why I asked how many sensors you were using with this one screw terminal board. In order to connect two Turner analog sensors to a Mayfly Logger, it’s good to use 2 separate s…[Read more]
Shannon Hicks replied to the topic Purchased wrong solar panel? in the forum Mayfly Data Logger 1 weeks, 4 days ago
If your station is in an open location that gets several hours of direct sunlight every day, then a 2W panel is probably sufficient if you have a cellular modem on your station. The 2W panel is definitely sufficient if it’s just a Hyrdos21 sensor and no telemetry. But if your station is under tree canopy or is mostly shaded, the P105 model 5W p…[Read more]

I was getting the same error message as the poster above, so I went ahead and followed the instructions that Shannon provided to fix it (2025-01-22 at 2:07 PM), but now I am getting this error message that I attached. That is one of 10ish errors that I am getting.
When checking out the libraries folder, everything seems in order.
The previous…[Read more]

Hi,
I bought the 6V 2 W ETFE solar panels from Voltaic to replace some 6 V 2 W solar panels we lost for our Hydros 21 setup. When I got them in the mail, I realized they were about half the size of the previous solar panels. I can’t tell from the specifications if they’re a sufficient replacement, would they provide enough power to power the…[Read more]

<p style=”text-align: left;”>I’m just connecting one Turner phyco c-flour sensor.</p>
I assume these resistor pairs are independent and shouldn’t affect how a single sensor reports.
<p style=”text-align: left;”>Thank you for the previous response regarding the cable glands.</p>

Are you trying to measure 2 analog signals from 2 separate sensors with just one 6-pin screw terminal board?
nick replied to the topic Continous HAB monitoring in the forum Mayfly Data Logger 1 weeks, 6 days ago
Shannon, I went ahead and soldered four 10k resistors instead of the two I originally said, similar to what you did here:
Does that still work for my purposes or does it change things?
Thank you.
Shannon Hicks replied to the topic Logger not transmitting data to website in the forum Mayfly Data Logger 2 weeks, 5 days ago
That happens occasionally when the connection between the Mayfly and the online time server gets terminated before the entire timestamp gets transmitted, resulting in an incomplete timestamp, and the Mayfly code has some smarts to check whether the timestamp it received is a valid, reasonable date. If you ever get this error, you can just…[Read more]

I have a new logger that is recording data to an SD card but I get the below error and the logger will not transmit to the website.
“Current clock timestamp not valid”
