How so? When replanting clear cuts here in Sweden with pine or fir each tree takes a few seconds to plant - you stamp your tool in to the ground which makes a hole, drop the plant down, stomp the ground and then your off to the next. There is also no need to tend to them afterwards (except treatment to deter deer/elks).
Exactly. A low end micro-controller would do the trick but a Raspberry Pi is much more accessible - almost anyone can get one fairly quickly and if they themselves don't have the knowledge to do the setup they most likely know someone who can help.
I learnt a little a few years ago while setting up monitoring and building a "Parakeet" [0] for a relative. I think the Nightscout foundation [1][2] should be a good start. I believe they are very active in their Facebook group.
Yes, the Raspberry Pi models are a little confusing, especially with the '+' versions and PCB-revisions. But I don't think the purpose of the parent comment was to say that it was worse than others, more of a heads-up to someone looking to order a model to take a second look and verify the specifications.
I have an YubiKey 5 NFC on the keychan and it has handled the abuse over the years just fine.
