DIY ESP32 Weather Station (connected to the Internet)

Published at : 23 Dec 2025

Today we build a complete weather station for less than 50€! This weather station measures Temperature, Humidity, Wind Speed and Direction, Air Pressure, and the amount of rain that falls. I built myself the anemometer, wind flag and rain gauge, while I bought the temperature and pressure sensors, that cost a few euros. All the sensors are connected to an ESP32, which sends the data via WiFi to Home Assistant.

All the details, the files to be 3D printed, the software part and the wiring diagrams can be found in the written guide: https://www.instructables.com/DIY-Weather-Station-With-ESP32/
