Your code looks close to what I am trying to do with the Atlas sensors. However, it wouldn’t compile due to missing SDI12.h library. Is this just for the SDI-12 protocol which I am not using for the Atlas senors?

I want to time stamp data to a log file from the Atlas sensors. I can’t seem to find any sample code for the Mayfly board’s RTC. I could also use some help on the battery and solar cell connections.

Thanks

I have test code from atlas scientific that works.

What changes do I need to use the mayfly board other than changing the board type in the IDE?

Thanks Steve.

That works but I noticed the 5V pins were at 3.27 Volts and the 3.3V pins were at 3.32 Volts. Is there another pin to turn on the 5V boost ckt?

I am trying to interface the subject conductivity sensor to the Mayfly. For starters I can’t find any info on switching the power to the grove connectors. The EZO sensors have a serial output that I want to use to log data to a file.

Any code examples for powering the grove connectors and a serial interface would be helpful.

I received my starter kit a few days ago and could not connect to computer (surfacw-win 10) although my system worked fine with an arduino uno on another project.

The cable that came with the kit was apparently defective because the system worked fine when I used another usb/microUSB cable I had. The defective cable supplied power but no…[Read more]
