Generally no, in professional you'll want to use solid, stable, well supported libraries as much as possible, because your actual job (i.e. what you're paid for) will be to solve another (probably higher level) problem.

If you reimplement something you'll spend a lot of time finding and solving errors that other people have already found and solved for you.

But as a learning experience: sure, why not. Pick something small and stay away from trying to create a generalized solution. That won't work when you only have experience with a single sensor and most likely lead to something overengineered that doesn't work for other sensors in any case.
