Jim Moore replied to the topic MMW Site Download Sensor Data in the forum Monitor My Watershed 3 days, 19 hours ago
I note the data server is still down. My Mac response is attached. “download.html” doesent show in my download file which I assume is because file doesn’t exist. Any update on the status of a fix?
Thanks

I tried to sign in today to pay for the GMI medium plan at $49/mo. The store doesn’t recognize any of my credentials. Do I need a different account?

Is there any chance to provide a finer price structure? Perhaps a fixed amount (~$5) per station with some discount for larger quantities. For example going from 3 to 4 stations would cost about four times as much per station! Also I noticed that there is a price break for a full year subscription for the small plan but none for the medium an…[Read more]

Thanks for the input, Dan@wachusett. I think I figured out my problem – it was the bubbles in the stream as you can see in the attached photo when I was co-locating two sensors! I moved the sensor probe about a foot to calmer waters and now the results look normal.

I have a Mayfly sensor station on a small perennial trib to Marsh Creek. I was noticing step changes in the EC of over 100µS in the 5 minute sampling interval. Suspecting that this was a defective sensor so I co-located another sensor and got a similar result and the two EC readings were uncorrelated. Therefor I put both sensors in a filled bu…[Read more]

The MMW server is working now but there is a data gap between 5/12 @15:00 and 5/13 @ 07:15. Will that data be restored or will we need to rely on the station SD card?

I have been getting “server error(500)” for the last two days on all stations I attempt to load.

@shannon I noticed that the specs for the Hydros 21 indicate 4.0 volts minimum. The junper on the Mayfly board is set for 3.3 V. Would you recomend changeing that to 5.0 Volts?

Thanks! I’ll plug that into my code.

@shannon I am setting up a new sensor station using the hydros 21 (due in tommorow) but I am not using the turbidity sensor. I deleted that section of the code but I wanted to add the humidity sensor. What do I need to put in the variable list? Here is what I have:
Variable* variableList[] = {

Some LiPo batteries have the JST connector reversed and that may be your problem. Check the battery with a VOM to make sure the red wire is + and black is –

@shicks. I tested the converters you recommended and they appear to work as expected:
dropout voltage is 8 Volts and will support input voltage to 31.5 V (max on my bench PS).
No load draw is 3.64 mA at 12 V and 2.83 mA at 31.5 V.
A lower cost option is a three terminal non-isolated converter at $2.76 ea vs $12 for the PlusRoc.

Thanks! I just ordered two. My four port sampler project uses 12V motors which draw about 0.4A so I guess that would be an option to use the 12V output and LiPo 3.7V batteries.
I assume this converter uses switching so it should be reasonably efficient. I’ll le you know how they work. Good old amazon – I should get them tomorrow!

Hi @shicks I got my 5 pack of the v1.1 boards today and I noticed that:
- Removed External/Lipo slide switch since it’s no longer needed
Does that mean I can no longer power the Mayfly from a 12 V supply? I have an application for water sampling and the pumps run on 12V and they are controlled by the Mayfly so I can power the whole system wit…[Read more]

It may be that MMW doesn’t like the underscore. I had a similar problem when I used # in the name of my stations.

I assume that the NeoSWSerial function is needed. to talk to the sim7080 and that is why I am not getting any response from the modem
