  I used the Mayfly 1.1 board and the sketch below. Thank you for helping me!

  Example B: Changing the address of a sensor.
  This is a simple demonstration of the SDI-12 library for arduino.
  It discovers the address of the attached sensor and allows you to change…[Read more]

  When you changed the SDI12 address of the turbidity sensor to “2”, did you use the same Mayfly board and the  “SDI12/b_address_change” example sketch that comes with our libraries, or did you change the address with a different board or instrument?

  There’s an example of using an Arduino as an SDI-12 slave in the Arduino SDI-12 library.

  Thank you for the response Shannon. I stripped and tinned the wires on the sensor, connected it to the 6-pin screw terminal as directed, connected the screw terminal with a grove cable to a SD-12 port on a Mayfly 1.1 board with the jumper moved to the 12v position. I also changed the sensor address to “2”.   For some reason, I am getting an e…[Read more]

  Hi James, if you have the spare jumper cable sockets you could try it and it probably will work.

  The challenge is the Mayfly doesn’t have a lot of capacitive buffering and the LiIon battery performs that function.  It might be more reliable to have a battery on each Mayfly and run the solar panel to both.  Of course the boards need to be kept p…[Read more]

  This is very interesting @neilh20 ! I learnt something new reading up on HEX- and INI-files and it would be of great help with a method like this.

  I will try your examples and see if I can be of any help.

  Thank you for feedback.

  I didn’t think about publishing it on GitHub at first as I felt like there are just two small pieces of Python program and it is all already available in that post. But maybe it is good idea anyway for possible issues reporting and improvements…

  No, I have never used Mayfly logger. When I found out about that project it…[Read more]

  Hi,

  I am having problems with the interference between MODBUS and SDI12 sensors on a Mayfly v0.5 board.  I can remove either one and the other works perfectly, but together I end up with around 20% -9999 values, usually for the SDI12 CTD.  I am virtually certain this has to do with the home-made modbus wing that I have built for this system.  I…[Read more]

  Wow thanks so much for sharing, and no problem with your English.  I’ve been in that situation where its difficult to debug ModularSensors/Mayfly as the software implementation using time loops is so time sensitive.

  Are you planning on using a git to store the programs with an open source license? Its very nice if you do and gives some…[Read more]
