Hi there and I am happy to become a part of this project. I would like to speak with a person regarding equipment and setting up a monitoring system. Friends at other watersheds have indicated that stream equipment/ system trainings are available. How do I locate these classes?

The file is there. Is your computer behind a firewall that is blocking github? What happens if you click on the link for the EnviroDIY json file? You should see a simple text webpage with some code talking about packages and platforms.

Hello,
I keep getting an error message when trying to download the EnviroDIY ATmega Board via this link on the software page:

Shannon Hicks replied to the topic Inconsistent and erroneous analog differential measurements in the forum Mayfly Data Logger 1 year, 10 months ago
Can you email me your code at mayfly@envirodiy.org so I can take a look at it? How many other adafruit ADC boards do you have attached to the Mayfly in question and are they the 12-bit or 16-bit versions? The Mayfly’s ADC is permanently set to 0x48. What is the typical and maximum voltages you should see on the sensor?
Shannon Hicks replied to the topic Continous HAB monitoring in the forum Mayfly Data Logger 1 year, 10 months ago
The two sensor models perform exactly the same. We’ve used a couple in the field with existing loggers when replacing some old broken Cyclops 7f sensors. All we did was swap the sensors and redo the calibration and edit the appropriate 2 lines in the code for the voltage measured in the standard and the blank (nanopure water). The C-FLUOR se…[Read more]

<div>Hi Shannon,</div>
<div></div>
<div>I ordered a C-FLOUR not realizing that the modular sensor library only has compatibility with the Cyclops-7F, even though you mentioned the Cyclops in your earlier post.</div>

Braedon started the topic Inconsistent and erroneous analog differential measurements in the forum Mayfly Data Logger 1 year, 10 months ago
I am having some difficulty getting consistent results using the Mayfly’s auxiliary 16-bit ADC. I have multiple stations set up that use the same code and wiring, but for some reason the measurements being recorded are not behaving as I would expect. For context, I am using Apogee’s shortwave pyranometers (both upward and downward looking) on the…[Read more]

Hi, has anyone used a Seametrics CT2X CTD sensor with a EnviroDIY datalogger? We are currently using these sensors and are looking into replacing some datalogger boxes.
