Hi All. I was playing around with measuring LTE signal strength and directionality with a cell phone yesterday. I’m wondering if anyone has a sense of the dBm threshold where the LTE modem will connect and upload data to MMW?

The limitation of these apps is that you can only measure the signal strength for your carrier.

A volunteer I’m working with received spam posing as an EnviroDIY forum post. Just FYI. See attached.

I’m curious, were those LTE XBee3’s deployed in the field, worked properly then at some point stopped connecting to the internet? Or did you receive them and realize they wouldn’t connect upon initial testing? Just wanting to understand if this is something I need to watch out for with our LTE stations we’ve already deployed.

Thanks

The SD card did have data. I left the SD card in long enough to complete one measurement. Attached. I then removed the SD card and took it home to look at the data, but left the station running without an SD card because I didn’t have a backup on me at the time.

Hi All,

I’m uploading data to MMW and wanted to share some observations.

1. Larger files will not upload successfully. It seems like the sweet spot is 11-13 days of 5-minute interval data for CTD/Turb Mayfly Configurations.
2. The data is sometimes visible on Time Series Analyst after upload and sometimes it is not. I can’t figure out what…[Read more]

Hi All,

Just following up on this. Shannon and I have exchanged emails off of the forum about setting up the Mayfly to work with the Yosemitech Sensor. Shannon, I’m curious as to the status of this?

Thanks,

Jake

Thanks Shannon! I’ll see what I can do.

Hi All,

I have a station deployed in a location with marginal cell coverage via AT&T. Verizon seems to be have better coverage. Can we update the Mayfly to send data through the Verizon network?

Thanks,

Jake

lemon started the topic Voltage Threshold for Data Upload Through Cell Network in the forum Mayfly Data Logger 5 months, 2 weeks ago

Hi There,

I have a couple stations that we deployed in forested areas. After a couple weeks the battery voltage settled at around 3.7v, dropping below that at times and rising above at times. When the voltage drops below 3.7v our logger stops sending data through the cell network. Would it be possible to decrease the threshold and see if we can…[Read more]

I’m trying to upload a csv file downloaded from a Mayfly station to data.envirodiy.org. I’m getting an error message that states “Failure to upload data. This file corresponds to another site”. I’m certain that this file came from the site I’m attempting to upload it to. I suspect there is a formatting issue with my csv. I’ve attached csv here.…[Read more]

Are there plans or instructions available for building/programming a 4G signal tester?

Thanks Adam!

Has anyone set up notifications when Mayfly logger stations data exceeds a prescribed threshold? For example, if conductivity were to exceed 500 us/cm an email would be sent to a designated email address.

Thanks for the great info all!

If I were looking to add the Yosemitech standard model to a Mayfly Station with a CTD and Campbell Turbidity sensor would I need to enhance the power capability? Bigger battery…bigger panel? Do you have code for the Yosemitech? Are there other considerations I need to take into account?

Thanks again.

Any suggestions on continuous total phosphorus sensors?

I’m working with a watershed groups located in a watershed with intense CAFO activity. They are interested in monitoring DO continuously using the Mayfly EnviroDIY Monitoring Station. I was recommended the Zebra-Tech Optical DO sensor which costs nearly 3500. I’m sure this is a great sensor but is a little expensive for this group. Any…[Read more]
