This one is basically similar in spec to the beaglebone and has -40℃
to +85 ℃

There's likely a number of other ones based on the TI am33xx and
they
should be straight forward enough to support Fedora with device tree
bits.
Thanks. The Forlink 335x device is almost exactly what I was looking
for. I have also one AM335x Sitara for testing, so it will be easy for
me to move there.
You'd need some sort of industrial board with appropriate
ratings. The
problem with that is they also tend to be expensive.
I consider Forlink as cheap. I think, I can can go for something more
expansive than this one. I would like to have more memory.
I'd differ from Peter's opinion and say instead you should go for
something very cheap, on the basis that you can easily replace it if
it breaks. A10 OLinuXino LIME (about $30) has several GPIO
connectors. It is supported by the Fedora AllWinner Remix, and I
think by the main Fedora starting in Fedora 21(?)

Thanks. I have very good experience with allwinner a10. It is one of
options. We plan up to 20 devices, so I want to decrease maintenance
costs.

You seem to have got something working already, but out of interest
did you consider a 1-wire weather station, and then just connecting
that to an ordinary computer which can be located far away and inside
in the warmth?
I am aware of that option. Also, I was about to buy professional weather
station, but it cost is ~600 USD and I need to buy additional computer
anyway. I was looking around on other projects [1, 2], but finally I
decided to create something new. We can discuss and explore other ways
how to get such device, but I don't want to go to much into offtopic in
this mailing list.
