This is a great book that really helped me use this sensor. It also uses an LCD (I used one I bought from seeedstudio, the brick one that they don’t have anymore in the shop, I see)

I see the author posted the schematics for this project. Unfortunately I don’t see arduino sketch and I don’t think I’m allowed to post it here. Too bad because the only thing I changed in his sketch was the constant (7.5 instead of 4.5).
But I really believe the book is really worth checking.
