Weather Station with BME280 Sensor

Introduction

Building your own weather station is both educational and practical, providing hyperlocal weather data for your specific location.

The BME280 is a precision sensor measuring temperature, humidity, and barometric pressure via I2C or SPI interface.

We'll use the I2C interface for its simplicity. Connect SDA and SCL to the appropriate pins on your microcontroller.

Store readings in a database for historical analysis. We'll log data every 5 minutes to build up useful trends.

Create a dashboard to display current conditions and historical charts using Python Flask and Chart.js.

Add a rain gauge, wind sensor, or integrate with weather APIs to compare your readings.
