Weather stations are interesting projects for beginners and very useful for expert makers. They are usually quite simple to build but also provide fairly accurate and useful weather data. We have built a couple of them in different tutorials on this website, with the difference usually being, the combinations and sometimes the accuracy of the sensors used.
