Good afternoon, I want to hang an arduino in the car, and the question arose: can it work at -35 or humid air? can it "freeze" or just stop working?

For the atmega328 itself, the operating range is -55..125 degrees. It is necessary to look at other components, such as usb / ethernet controllers, there may be more stringent restrictions. Humidity is more difficult, but usually condensation is not allowed anyway. Another thing is that it is definitely not worth using the option in the crib for extreme conditions. Well, if you want to operate in a car, then you need to take vibration into account - the wiring that you connect to the expansion connectors can stupidly fall off. In general, you can try it as a fan, but I would not recommend connecting vital controls;) Well, a watchdog must be used for such applications.

ATmega328/1280/2560 operate in industrial temperature range -40..85 ( ATmega328 characteristics for example).
The rest of the components on the Arduino board use the usual range (from 0 degrees) - so you need to be careful. Expansion boards - you also need to look, for the most part they use microcircuits with a standard temperature range.
If the “computing unit” is sealed, then there should be no problems with humidity (it does not heat up so much to be forced to ventilate, but filling it with epoxy is also too much). Connection connectors must be appropriate.
Regarding the stability of work and freezes - it all depends on the programmer :) as he writes, so he will work.

Mockups are not meant to be run all the time, they are meant to be developed and debugged. Dilute a plow for a specific task and order / manufacture it, it will turn out reliably and beautifully.

If possible, tell us what exactly it will be used for, and where do you want to install it?

Arduino is a prototyping tool. In short - the designer.
In principle, if you connect the modules well, it will be more or less reliable.
Operation in a wide temperature range is not provided even by branded motherboards, I generally keep quiet about Chinese ones, the same applies to high humidity (if it can be varnished). Everything and always hangs up, for this there is a watchdog. True, this function does not work correctly in all Arduinos, it is treated by flashing the bootloader
