According to the product change notification you attached, there shouldn’t need to be any software changes for “transparent” mode, so most of the examples for ModularSensors should still work.

The underlying cellular chipset on the board *has* changed from the ublox SARA R410M to the Telit ME310G1-WW on the global version or the Telit ME310G1-W1…[Read more]

You can also try disconnecting the solar panel for a few days since you’ve got a fully-charged battery on it.  Then that’ll tell you if there’s any correlation between the sensor noise and charging activity.  On a few rare occasions, a failing solar panel ended up generating noise on CTD sensor data.

Yeah – the sensor was cleaned recently. I had also switched the logger on and off. I’ve now replaced the battery. No luck – the trough and flickers, though slightly modified, still occur. I’ll try to substitute in another sensor, possibly another logger, in order to isolate the problem.

Thanks Shannon! Some testing and an example sketch would be very helpful.

That’s a good find.  We haven’t tried one of those with the Mayfly boards yet, but we’ll have to buy one and see what all might be needed to get it to work properly.  Previous Digi boards required our now-discontinued bee adapter board to change the pin assignments and power supply options in order to work with the Mayfly v0.5 boards.   But the…[Read more]

@tumayflybearriver – thanks for brining it up.  Its nuts, but  looks to me like the signature of  “thrown away data” by  ModularSensors software that runs on the Mayfly, and the ODM2  software on monitormywatershed.

I’ve raised the issue of reliable delivery in 2018, and implemented it on my systems and offered it to the mainline Modu…[Read more]

Have you been to the station to clean the sensor lately?  Also, I’d recommend replacing the logger’s battery with a fully-charged one.  Sometimes when those battery packs are starting to fail (from corrosion on the terminals under the plastic wrapper) they will generate noise which can sometimes affect the sensor readings.

No, the Mayfly datalogger doesn’t know if any data is missing from the website, it just tries to send it every 5, 10, or 15 minutes (or whatever interval it is programmed for).  If the data doesn’t get to the website database, the logger won’t know, and doesn’t send any old data to fill in the gaps. You’ll need to visit the station and manually…[Read more]

I’ve been swamped lately, so I’m behind on sensor requests.

<div>@fionasouthwell Are you sure you’re measuring *specific conductance*? From what I know of the Atlas sensors, they don’t measure specific conductance, they measure conductivity. I just very quickly skimmed their latest manual and it doesn’t look like that’s changed. To get…[Read more]

Hi Fiona, @srgdamiano may be able to help you with this. There is also a pathway within the Monitor My Watershed site itself for making sensor requests. I’ll describe it here in case it is also helpful to others.

When adding a new sensor to a site on MonitorMW, if you don’t see what you need in the Add New Sensor modal window, scroll to the…[Read more]

@shicks I’m also going to be adding an air temperature sensor that has a 12-volt fan in the radiation shield. The fan can run at lower power by using pulse width modulation. I’m wondering if there might be a way to accomplish this with the power relay, since the fan will have to be connected directly to the battery like the heaters on my other…[Read more]
