Shannon Hicks replied to the topic AM2315C Compatibility in the forum Monitor My Watershed 2 days, 11 hours ago
I’m not familiar with the new C model, but I did use the older, now-discontinued one awhile back. Without digging into the manual and the library too deep, I’m guessing it might be an I2C address issue? The old model used 0xB8 whereas the new one uses 0x38. So go into the ModularSensors/src/sensors folder and edit AOSongAM2315.cpp, find line 34…[Read more]

EnviroDIY Modular Sensors has the AOSongAM2315 but not the new AM2315C. I have the AM2315C. Is there a way for me to integrate the newer AM2315C sensor into my Mayfly project? I have the wiring ready. I have successfully tested the sensor and received good values using an example program so I know the sensor works but when I use the AOSongAM2315.h…[Read more]

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 5 days, 6 hours 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 1 weeks 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.

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 1 weeks, 1 days 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?
