MMP replied to the topic Could not wake modem for clock sync. in the forum Mayfly Data Logger 2 years, 4 months ago
Hi!
I was hoping to piggyback on this thread since I am having a similar problem with the clock sync and LTE connection. I am also working with a 1.1 Mayfly model with LTE Bee, hologram, and a Hydros 21 CTD sensor.
So far I have tried several locations with full LTE coverage through AT&T, reprogramming the Mayfly to make sure all changes…[Read more]

This looks like a great option. Thanks Shannon for your help!
Shannon Hicks replied to the topic Controlling 12-volt heaters with a power relay in the forum Infrastructure and Equipment 2 years, 4 months ago
That’s not much current, so most relay boards should be able to handle that with no problem. I think that latching Grove board (https://www.seeedstudio.com/Grove-2-Coil-Latching-Relay.html) would probably work good for your situation so your Mayfly board could activate the relay 15 minutes before you want to sample, and then go back to sleep and…[Read more]

I have four sensors with heaters, and combined they draw 61.6 mA.
Shannon Hicks replied to the topic Controlling 12-volt heaters with a power relay in the forum Infrastructure and Equipment 2 years, 4 months ago
What’s the current draw of your heaters? There’s a variety of relays you could use, but I know several people have had good luck with various Grove-compatible relay boards, like the ones from Seeed. But your options are going to depend on how many amps of current the heater draws from the battery.
Braedon started the topic Controlling 12-volt heaters with a power relay in the forum Infrastructure and Equipment 2 years, 4 months ago
I have some apogee pyranometers and pyrgeometers for my monitoring stations, and each of these sensors has an internal heater that helps to clean off snow, rain, and frost. The heaters operate at 12 volts, so I have them connected directly to my 12-volt battery which powers my entire setup. Having the heaters connected 24/7 draws a lot of power…[Read more]
merondibia replied to the topic SDI-12 Library in the forum Other Data Loggers 2 years, 4 months ago
I am trying to update a data logger which was using Arduino Mega+SD reader and us Arduino GiGA R1 in order to monitor it remotely, but SDI-12 library is not working on the new Arduino GIGA board, Is it possible to use your fix to update the library for this set up?

Its some good thinking and takes time to scope it. From what I understand, some of the AI on vision detection may have a lot of promotion without understanding what it takes technically to make it reliable. I’ve […]

Hello Neilh20 Sorry for the slow response. As mentioned as an aquatic ecologist I am more on the end user side of the insect camera trap development than the front-end design and am grasping about 40% of the […]
