fisherba replied to the topic Testing Data Uploads to data.envirodiy.org in the forum Mayfly Data Logger 5 years, 11 months ago
While it’s true that there’s no “testing mode” at data.envirodiy, I do test the communication before I deploy by just setting the station up and let it start running. My last test ran for just over 2 days and one station died at 1.5 days because I didn’t have a powerful-enough battery. I was grateful to have it running for long enough to tell. I’m…[Read more]

Hey @klstokes, especially if your students are already producing a written report, please encourage them to format it as a blog post so others can learn from their process!

Thanks for sharing! It looks great!
It looks like it holds the potential of flooding. Have you installed submersible cord grips? https://www.mcmaster.com/#standard-cord-grips/=1cm2uit

Kevin, I was just thinking, how about mounting a PVC end cap to the back of the pelican case (so the door of the case is on top) and drill and tap the PVC and case to accommodate the ultrasonic sensor? It would look something like the one linked above, but roomier. Then you have the case mounted as a sort of well cap and you have room to add…[Read more]

Hi Kevin, I’m not sure about an elegant way to mount a pelican case to the pipe. My current cases are all pole mounted with two 10″ zinc mending plates mounted to the back of the Pelican case using bonded sealing washers to keep the case dry. Then the mending plates are mounted to a post in the ground. If you have only ultrasonic sensors on the…[Read more]

Hi Dave,
I have a version 3 and a 5b sitting next to me and both have the version number right by the on-off switch. It’s also printed on the back of the Mayfly to the right of the name.

Is it possible to power two Mayflys on one battery/solar panel? If so, I would appreciate ideas on how to connect them.

Scripts are available in the modular sensor repo: https://github.com/EnviroDIY/ModularSensors
Also notable, we like to drill and tap plastic enclosures and screw the MaxSonar straight into the enclosure.

I have a couple of high school students making a water-depth sensor with the MB7389 ultrasonic sensor and a Mayfly data logger. The information you posted has been very helpful. We are also using the Pelican 1120 case. The problem we are having is attaching the case/MB7389 to the top of the 4″ PVC pipe that we are using for a stilling well. Any s…[Read more]

Thank you. I checked out the link, that is very nice. Right now we only have the ultrasonic sensor, but I wanted to add temperature sensors for water and air. In the future, we might add a rain gauge.

Hi Kevin, we are using and like the sensors from Maxbotix. Here’s an old blog post by @shicks to see one compact enclosure option: https://envirodiy.org/ultrasonic-water-depth-sensor/.

Hi all,
