A data handling unit interacts with a device driver supporting a piece of
hardware. The hardware could be replaced in the future with another
hardware. What pattern should bed applied better in such situation? Is
Strategy a good choice?

I read somewhere that Facade-like wrapper could be better candidate for the
problem, but don't understand how it could be. If this is true, could
someone elaborate on this please(some code will be great help)?

Thanks for your comments!
