  Shannon,

  Thank you for the confirmation and write up for the sketch setup. I just have the phycocyanin C-FLUOR. This is my first time soldering, so I’m practicing on another board before I commit on the MP screw terminal board.

  Have you notice big differences between the calibration sheet versus your manual calibration? And for the manual…[Read more]

  Yes we are using a Mayfly v1.1! As for the 12v source, I am not too sure. I did not put the board together originally so it’s been operating how it’s been since it was put into place.

  I will be back soon to check on it again with a voltmeter. Could you explain how I can check if it’s using the correct 12v configuration?

  Much appreciated,

  Elliot

  I assume you are using a Mayfly v1.1 board and not an older v1.0, because it had a hard time providing a stable 12v for that particular type of sensor.  But are you using the onboard 12v source by selecting 12v on the Grove voltage selector jumper, or are you using one of the new screw terminal boards that has its own 12v boost circuit on it?

  There are no workshops scheduled yet for 2025, but you can review past events and check in from time to time for new events under the Participate tab, https://www.envirodiy.org/envirodiy-events/.

  That all looks correct.  I usually put the Mayfly’s analog Grove jack voltage selector jumper to the 5v position because the old sensors required 5v for excitation, but supposedly these newer ones are happy with 3v to 15v, but we still use them at 5v and calibrate them with that excitation voltage.  If you connect the 6-pin screw terminal board s…[Read more]

  Shannon,

  I attached a picture of how I am connecting the C-FLOUR to the multipurpose screw terminal board. Can you let me know if this is the correct wiring and resistor amount, type, and location?

  Thank you.

  We installed a ClariVUE10 turbidity sensor with a data logger in a creek a couple of months ago. It was working well and uploading data to MonitorMyWatershed.org without issues until 10/17, when it started reporting -9999 values for turbidity. We’ve verified that the sensor wiring is intact, and the internals of the logger appear to be f…[Read more]

  Hi,

  Was a firewall at my school…got it fixed now. Thanks a lot!

  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?
