I have the same issue.  I have my LEC stations (GMI_ECxx) running with 2G cell service and I did have one station that the solar charge chip failed and caused battery to drop below the 3.55  volt threshold for upload.  However GMI_EC5 seems to be getting a charge during the day but is still not keeping up.  I attached a screen from MMW…[Read more]

It looks like this power sensor from Adafruit could work: https://www.adafruit.com/product/4226

This sensor, with accompanying library from Adafruit, returns milliamps, millivolts, and milliwatts via I2C, so seems promising.

This is new territory for me, so if anyone has insights or advice, I’m happy to hear it!

Hi Anthony,

Thanks for your reply. I will have to check out the LoRa radios you suggested. I’ve been looking at the ModularSensors library as well. I’m am also checking with the project sponsor to see if there is a reason that specific LoRa radio module was chosen.

Thanks again!

Hi Anthony, I would also be available for testing/helping integrate LoRa networking and I have some gateways. Wow great news to hear there is an implementation done.

For my local SSU I volunteer as Industry Advisor, and for last years Engineering Capstone project a student used an Adafruit LoRa module on a raspberry pi pretty effectively.…[Read more]

We’re planning to implement a separate online storefront for bulk quantities for instances like this, which will make purchasing large quantities much easier than buying lots of our single-packaged units from Amazon. Not sure of the exact date we’ll start, but hopefully very soon. In the meantime, if you just need estimates on when a certain…[Read more]

Hello I’ve just had a request to quote for a number of water monitoring devices, each one includes a Mayfly. I’ve put on the response quote subject to availability of the Stroud Water Research Center’s Mayfly.

Is it useful to be able to indicate potential demand?. Its a pretty typical thing for selling that there is a demand forecast.
Some…[Read more]

Matt, LoRa is a big leap beyond the Xbee 900 MHz self-meshing and local network stuff.

Shannon set up an Xbee 900 MHz network for us in 2012, which I think is still in use. Short story is that 1 km range is max and bandwidth is low for standard HTTP Post requests.

LoRa is much longer range (5-10 miles or more) and lower power. It does this with…[Read more]

Hi all,

Glad to hear about others using radio modules to relay Mayfly data to in internet connection. And Anthony, it’s great to hear about the mDot modules potentially being incorporated in ModularSensors. That’s something that we at Trout Unlimited will definitely be interested in exploring in the coming months. I could possibly contribute some…[Read more]

Dale, I’m not familiar at all with the Semtech SX1272MB2DAS Shield LoRa radio module.

I am, however, quite familiar with the MultiTech mDotTM LoRa radio modules, which come with an XBee interface that plugs right into the Mayfly and works without any trouble. My colleagues at LimnoTech’s Ann Arbor office have been using them successfully in the…[Read more]

They were in stock and available for a few weeks, but I guess they’re popular again. We’ve been offering the protoshield for several years, but demand for these tends to fluctuate more than any of the other things we offer, so it’s difficult to predict.

A tip for finding our items on Amazon: only in-stock items can be found using the Amazon…[Read more]
