I wasn’t suggesting a known solution that for instance I’ve seen. I was suggesting it based on the general guidelines for the type of project. Moisture data doesn’t need to be secure. The transmission doesn’t need to be real time and you want low power consumption so that each sensor lives a long time on a single battery. Since the information, or most of it is going upstream, RF seems the way to go from my perspective.
So with RF you get a lot of benefits and of course low cost hardware!
