I found this interview very interesting. I have a 10 acre olive grove I remotely monitor with a system I have been developing for a few years now. It runs off grid with some solar panels on top of a shipping container and a 600 ft. well. Took some time of get something powerful enough to run the well, but sip energy to ride out a string of cloudy days and reliable enough to run remote. I am in Orange County, Ca.
I used an Arduino, Raspberry Pi, cell modem, and a handful of custom circuit boards I am working on polishing up to see if they may have value to others.
This is a side project from the day job working in aerospace.
