I have a solar powered box that will be set in the field at our farm to monitor soil and air temperature and soil moisture.
The temps are uploaded to the webpage via a cell phone connection using a Particle Boron.
4/14/21: New Boron arrived yesterday. Made a new case for the electronics behind a small solar cell. It's currently set in our
garden. Will move to our farm in the next few days if all goes well.
4/23/21: New Boron lasted 1 1/2 hours. Flashes red. Cannot reset. I am talking to the Particle Service Department and ordered another one.
From some of the documentation I read, I think the failure was related to it loosing power at a critical time as its LiPo battery drained.
The last report to my webpage showed the SoC (State of charge) at .10 so the battery was almost dead when I hooked it up. I
have ordered a large LiPo battery and will try it again. I'm hoping Particle will replace the failed Boron.
5/21/21: I finally got some time to work on this again. I did a reload on 2 software libraries for the temperature sensors and
the sensors have worked flawlessly for about 24 hours. That's a good sign. It's running off a 6,000 mAh LiPo battery.
Next thing is to build an enclusure for this big battery and hook up the solar charger.
