It’s hard to tell exactly what’s going on with your wires from the photo, but you should make sure your separate power supplies are sharing a common ground. If you’ve got 12v going to the sensor and 5v going to the board, you need to have the ground of both of those supplies (or batteries) connected to the same ground as the Mayfly.

Thanks for the reply,

Yes, I am working with Troy :). We have had some success with the decagon CTD, including using a wifibee and portable wifi hotspot to log data to monitormywatershed.org. It would be nice to have turbidity measurements as well, which is one reason we are interested in the Y4000 device.

In our y4000-mayfly setup, I have…[Read more]

Hello,

Thank you everyone for your help. These issues have been resolved.

You’re missing some rows of your header. That file will definitely not work.

At minimum, you need the text “Sampling Feature UUID: ” before that UUID and another row that specifies the UTC offset with the text “Date and Time in UTC-#” where # is your offset. You can put all the result UUID’s on the row with the feature UUID as you’ve done, as…[Read more]

I’m trying to upload a csv file downloaded from a Mayfly station to data.envirodiy.org. I’m getting an error message that states “Failure to upload data. This file corresponds to another site”. I’m certain that this file came from the site I’m attempting to upload it to. I suspect there is a formatting issue with my csv. I’ve attached csv here.…[Read more]

@rachel.murray, that’s great to hear that you were able to get the YosemiTech Y4000 sonde working with our Modbus Mayfly Wing Shield and associated documentation. I developed all of that for a team at Winona State University in Minnesota, but I hadn’t been aware of anyone else trying to integrate the Y4000 with our EnviroDIY stack. So that’s…[Read more]

Hello and greetings from New Zealand,

My work group is developing some mayfly loggers and we have run into a problem using Modbus with a Yosemitech Y4000 sensor, measuring pH, conductivity, temperature, turbidity, and dissolved oxygen. We are attempting to communicate to this device using the WingShield and Modbus (as described on the EnviroDIY…[Read more]

I edited your original post to put the code into the Code Snippet tool.

I check every one of the Mayfly boards thoroughly before they get sent out to Amazon, so it’s possible that one with an FTDI or USB jack issue slipped by since that’s the only part of it that I don’t check. Send me an email to mayfly@envirodiy.org and I’ll see what I can do…[Read more]

Since we are not using the screen any longer, I2C is also no longer being used.

No. If you are using either the DS3231 real time clock or the TI1115 analog-to-digital converter built into the Mayfly, you are using I2C. Both of those are I2C chips.

Hello,

Thank you for the information. I removed the unnecessary parts in my code, as we currently were not using the OLED screen. Since we are not using the screen any longer, I2C is also no longer being used. All switches on the two boards that were not working as well as the boards in the field are where they need to be, so that is likely…[Read more]
