2025 STEAM EXPO

PROJECT SUMMARY

This project is a weather station that can measure temperature, humidity, atmospheric pressure, wind speed, and precipitation.

WHY?

I decided to make this project so I can have more accurate readings of the weather in my exact location, because the weather forecast is not that accurate.

HOW?

So, firstly, I decided to use the DHT11 and BMP180 to measure temperature. for measuring precipitation, I designed a pluviometro, a little bucket with a magnet, and a Hall effect on the other side that detects when the bucket spills out. For measuring wind, I designed an anemometer that works like the pluviometer, but instead of seeing if the bucket spilled out the water, it measures the revolutions. I used a Raspberry Pi Pico W to send everything to the app, and finally, to power everything, I used an 18650 battery connected to a 6V 2W solar panel. For the structure, I used some 25mm PVC pipes and some 3D printed parts in PETG.

WHAT?

I learned how to charge 18650 batteries with a solar panel and how to calculate precipitation and wind speed with a pluviometer and an anemometer.

SO WHAT?

I didn't finish this project yet, but this project helped me learn a lot about meteorology and helped me understand more about outdoors design.

WHAT'S NEXT?

This project isn't complete yet, I still need to make some tests with the solar panel, and finish the app and code for the Raspberry Pi Pico W.
