DIY Weather Station with ESP32

Overview

This guide details the construction of a smart weather station utilizing the ESP32 microcontroller. It is designed to measure and report environmental data, offering real-time insights and historical analysis.

The station collects data on temperature, humidity, air pressure, wind speed and direction, and rainfall. This information is transmitted wirelessly via Wi-Fi to a dedicated mobile application or a web interface. Users can monitor live readings, view graphical representations of data, and utilize pressure trends for basic weather forecasting.

For a comprehensive visual walkthrough and detailed construction steps, a video tutorial is available on YouTube. The video is presented in Italian and includes English subtitles for broader accessibility.
