[24] Weather station

Last Christmas, my brother gave me an Arduino starter kit. I’ve wanted to learn how to program it for a long time, and having this present was the perfect occasion to begin. So I bought a complete guide and started to play with it.

As I was learning, many project ideas came to my mind. One, in particular, stood up: what if I tried to build my weather station?

One of the many reasons Arduino is awesome is because of how easily and quickly you can try out your ideas. I picked up a few components and built a small prototype on a breadboard. How joyful I was when the actual data appeared first on my screen!

Once satisfied with to prototype, it was time for me to solder the components on the daughter board.

I used a DHT22 for temperature and humidity combined with a BMP280 for atmospheric pressure. The Arduino, on the other hand, is a Nano 33 IoT which I choose because of its low price and wifi connectivity.

I did my best to keep everything compact and easily repairable by using a small board and as many pinheads as possible. I also adapted my code to the Arduino Cloud solution (which was incredibly easy, by the way).

As usual, I like to keep things simple, so I put everything under a stool I use as a plant raiser. I just used an old Ikea box to protect it from rainwater drops.

I’m pretty happy with the result, considering I didn’t know much about electronics and Arduino only a few weeks ago. It’s surprisingly easy to learn if you catch the right resources.

But this project is only the first part of a bigger one, as I plan to build a magic mirror to display the data and a 3D-printed case. I’m also thinking about cutting the cord by using a solar panel.

Like always, I hope you enjoyed it as much as I did.

See you next time!
