Based on the photo, it appears the wiring is correct, assuming the orange and brown wires are inserted sufficiently deep into the header as to make a connection with the contact down inside the hole).

Your code is different from the latest a_wild_card.ino example that we include with the current SDI-12 library files.  Are you using an older…[Read more]

Can you describe how you’ve wired the sensor to the Mega, or even better, can you post a photo showing the board and whatever setup you’re using to connecting the sensor to it?

Are you at least getting the data in decimal format before you convert it to hex, or are you saying you aren’t getting any response from the sensor?

Can you post the code for your sketch, or are you using the simple parsing example exactly as-is?

The shipment arrived a few days ago, I’ll be documenting the new hardware and finishing the changes to the website later this week and hopefully have them available in the shop next week.

Sorry you got some backwards cables and a bad header.  I used to inspect all of the boards and cables closely before shipping them out, but in the most recent production run, the cables were sealed in a foil bag along with the adapter board, so we weren’t able to see them properly.  You can fix the backwards polarity cables yourself.  Just use a…[Read more]

New Mayfly boards and cool new accessories will be here very shortly, still waiting for the shipment, and then we’ll need time to turn things around and get the shop restocked, but it should be very soon.  We’ll be making a blog post soon about all the updates to the hardware and accessories in about a week or so, and then things should be ready…[Read more]

I haven’t used Thingspeak in a very long time, since we have our own data host at MonitorMyWatershed, so I don’t know the specifics about the connections, but I know a few other EnviroDIY members have used it, so maybe one of them can help out.

You shouldn’t have to use XCTU for anything, the modem setup part of the sketch programs the Digi module with whatever settings are necessary, based on what you’re trying to do in the sketch.  You’re able to connect to the internet, otherwise the clock syncing function wouldn’t say that your RTC is on time, so I’m guessing your issue is with…[Read more]

With such a small max signal of 200 mV, you’d definitely want to use the ADS1115.  The default ADC range has a resolution of 0.1875 mV/bit, which is pretty coarse so you’d want to use a higher gain setting like 8 or 16.  At gain 16, there’s a max input of 256 mV, and a resolution of 0.0078125 mV/bit.  Just be sure the ADC input doesn’t see any…[Read more]

The Mayfly can only read analog signals from 0 volts to 3.3 volts, so you’re not going to be able to read something that puts out 5 volts.  But from what I can tell about that sensor from a brief look at the manual, it only outputs a maximum voltage of 10mv.  You’re supposed to use it with a separate amplifier if you want to be able to read it w…[Read more]

Are you at least getting the ultrasonic sensor data to be stored on the microSD memory card but not on the website, or are you not getting any data from the ultrasonic sensor, even in the serial string that gets printed to the serial monitor after every reading?

You can ignore the warnings to the serial monitor about the UUIDs if you never intend to send data to MMW.  The warnings are just there to help people in case they were using the generic ones when they didn’t intend to.  But since that’s what you want to do, it’s okay to ignore the warning.

When you register a site on Monitor My Watershed you can set it up with various sensor parameters, and once you’ve got all of them entered on the website, you click the “View Token UUID List” button at the top of your site page and you’ll get a list of all the UUIDs in the exact format and order in which you need to paste them into your sketch. …[Read more]

Yes, the server was restarted this morning and service returned to normal, however all stations will be missing about 11 hours of data from earlier today.

Yes, we’re aware of if and the data team has been notified.  No estimate on when it will be back up yet.

There was a very small adjustment made several months ago to the delay time between commands to make communication with the Meter Group Gen 2 CTD sensor a little more reliable.  I don’t remember the exact date, but the latest release of ModularSensors definitely works with them.

I’m not familiar with that module, but the specs say that its default baud rate is 115200, so you should set your “modemBaud” rate in the sketch to match that, so something like:

const int32_t modemBaud   = 115200;

Was that the value you changed in your sketch?  Because it’s set at 9600 in the example you attached.  Have you successfully c…[Read more]

The current estimate is that we’ll receive a big shipment in about a month, so early August we’ll be able to restock the shop and Amazon.  The worsening electronics supply shortage caused me to have to make some changes to the Mayfly design based on component availability, and that delayed the fabrication of new boards until we could fully test…[Read more]

The entire electronics industry is facing growing supply issues that started last year.  I’ve been aware of the issue since early this year and started planning accordingly, so we shouldn’t have any supply issues with our custom EnviroDIY products.  But industry experts and suppliers are saying that components and products from companies like D…[Read more]
