As stated in the blog post about the new releases, I’m working as fast as I can to prepare all the products for shipment, and will be updating the shop and forum as soon as they are available.  The Monitoring Station Kit will take a little bit more time to be released because we’ll be changing the contents of the kit slightly.  In the meantime, I…[Read more]

I haven’t had any issues with any loggers not recording data recently or clocks not running, including boards I just programmed this week.  But I use stable libraries from several months ago and haven’t updated them recently.  Are you using all the libraries that are available in our suggested .zip file, found here: h…[Read more]

The we’ve found that loggers with the Digi cell boards on them have a tendency to act a little squirrely sometimes and give either erroneous readings or cause excessive power draw.  In you case, I’d start with putting a fully-charged 4400 mAh battery on your station and see how it performs for a few weeks.  If that doesn’t solve it, investigate t…[Read more]

The website reports on the last time data was received by the website via the cell modem.  So you’ll have data on the card that’s not on the website.  And there are 2 date/time columns in that data file, one is local time (standard) and one is UTC time.  They are 5 hours off if you’re in the eastern time zone.  So data points in the evening bef…[Read more]

Your battery is too low.  This is the same issue that was asked about last week:  https://www.envirodiy.org/topic/battery-failing-in-the-middle-of-the-night/

Anytime your battery voltage drops below 3.55v, the logger won’t transmit, in order to save battery power and conserve enough energy to keep writing the data to the memory card even though i…[Read more]

The data looks to me like the battery voltage dropped in July, someone replaced it with a charged battery on 8/4 and data was continuous, but then on 8/25 someone replaced the battery with the almost-dead one from earlier in the month.  And if you’re using the sample LTE logging sketch like what’s found here:…[Read more]

The shipment of new boards and accessories arrived 3 weeks ago.  I began testing the products and making the necessary changes to the code and documentation, but then our area was hit by the remnants of Hurricane Ida, several dozen of our stream monitoring stations were located on rivers that saw flood events greater than anything that’s happened…[Read more]

Sounds like it’s working, that’s a standard response string for that sensor.  Is there a particular reason you’re requesting the Mega to print the result in hex instead of decimal.

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.
