What are the latest supported sensors availble for the Mayfly systems? Is there a current list somewhere in the system?

I am not sure this is the correct place in the forum to ask this question. But here goes.

I have recently received a hex file for updating my Mayfly 1.1 data logger card. The procedure is written for windows PC. I have a Macbook Pro M1 MAX series machine running. Ventura 13.4.

The procedure calls for downloading the AVRDUDE software, dri…[Read more]

Where do you go to get current ManageMYwatershed status?

I am noticing that visualizer data service is not working.

We are installing a new Mayfly 1.1 data logger with the LIPO 4400mah battery, LTE Bee cell modem, and a ETFE 5W 6V solar panel, Hydros21 CTD sensor taking data at 15 minute data taking intervals.

My questions are as follows:

With this setup what is the amp hour usage of the Mayfly 1.1 datalogger using the LTE Bee cell modem and the Hydros…[Read more]

I am hoping that we can use AT&T or Verizon cellular. That will make things simpler(maybe). But it’s nice to get a toolbox of useable solutions if they are needed.

We have a deep canyon location that may or may not have cellular data coverage for real time data transfer to MMW site. I am wondering if anyone has done a 900MHZ radio with a Mayfly data logger point to point (bottom of canyon to top of a canyon) and then connected to a cellular network for almost real time data uploads? We will have a line of…[Read more]

Please help to clear up my thinking about these sensors.

This has probably been asked before, but after searching thru the forum I am not finding answers to this question. We have the Hydros 21 CTD sensor. It looks like this sensor is calibrated at the factory and the sensor reports engineering values to the Mayfly datalogger.

Is this ass…[Read more]

Thanks for the quick answer, too.

Thanks for the great answers. These are really helpful. There are so many things to dig into with this system. It is easy to miss some of your notes and instructions. I am finding that it requires a lot of deep diving into information. I am trying to build a process for our folks to follow that will be simple to understand. There a…[Read more]

When I first received the Mayfly V 1.1 a few weeks ago, I hooked up the all of the connections: Battery, Solar Panel, and sensor. Everything worked fine. Over the last week I have noticed that the yellow solar charging LED is not lit when the Sun is out. However looking at the CSV generated file the voltage is higher like the panel is cha…[Read more]

This may have been asked already.

The Mayfly v1.1 board. What is the temperature range that this board can stand for a closed up box? Also, we have the 4400mAh LIPO battery, Operating and charging with the solar panel. What is the min and max temperatures can this battery stand with a closed up box?

Thanks,

Rogers
