Thanks Connor! I looked up the Flowline, looks like bluetooth transmission? Love having options I can suggest to people, since people want to be replicate our program in some nearby watersheds. I like being able to give a range of options for their budget.

What is the monitoring project you’re using the Vega sensors for? Just wondering if it is…[Read more]

I’ve had a dozen or so Vega sensors in the field for about a year now. The quality is good, and the setup is super easy, but they’re getting pricey. I’ve seen some colleagues run the flowline sensors since they’re a bit cheaper, and they seem to be performing just as well: Flowline

I don’t really think you can go wrong either way.

If you want the updated library, start from the examples for the updated library.  It shouldn’t be too hard to update if you’ve mostly stuck to the example.  A side-by-side difference viewer would help to check what you need to change.  That being said, if everything was working well for you using the old version of the library, you don’t ne…[Read more]

Reverting back to the v0.33.2 library has fixed the issue. Is there something I can edit on my current script to work with the newer library or should I redo it using the DRWI_Mayfly1.ino example script that Sara recommended here: Library issues – EnviroDIY

I checked on the sd card and it looks like it is still recording data after it stops sending data to monitor my watershed, but everything is “-9999″ except for board temp and TrubLow just registers the last reading. I reuploaded the script, but this time I’m using v.0.33.2 library.

The sensor was getting 12V power. Every time I give SDI12 commands that wipes and measure the turbidity, the command would run (as evidence by wiper run) but it wouldn’t get any sdi12 command response. So, I used CR350 to change address from 0 to 1 and now it’s working correctly.

I’m not sure what you mean by “The page says 12V is the default” because the default Grove jack jumper setting of the Mayfly v1.1 boards has always been 3.3v.  You have to manually move a jumper if you want to select 5v or 12v for the Grove jacks on the Mayfly v1.1 board.  So verify that the jumper next to the Grove jack you’re using for the s…[Read more]

The page says 12V is the default and my sensor is getting 12V because I could send command to run wiper which needs 12V and it works. But data measurement command doesn’t work.

There are instructions on the Grove jack jumper settings on this page, including a photo showing examples of what the jumper position would look like for the different options:  https://www.envirodiy.org/mayfly/hardware/jumper-settings/

I am using Mayfly v1.1. The turbidity sensor is connected with Screw Terminal.
I downloaded the zip from EnviroDIY_SDI12 using https://github.com/EnviroDIY/Arduino-SDI-12/archive/master.zip.
I am able to run the wiper with these:

Serial.println("Sending 0M2!");
mySDI12.sendCommand("0M2!");
delay(1000);

Using this inside loop that runs every 30…[Read more]

What is the board version of the Mayfly data logger board that you’re using?  Did you set the jumper header next to the Grove jack to the 12v jumper setting?  Are you using the latest version of the EnviroDIY_SDI12 library?

I’d suggest trying a product called Goo Gone.  It’s a citrus-based adhesive/sap remover that is safe for use on plastic.  DO NOT use Goof Off, it isn’t safe for plastics and will damage the solar panel.  Rub a little Goo Gone on the sap and let it sit for a few minutes, then wipe it off and rinse it off with some soap and water.  It might take a c…[Read more]
