Important Notes
The BMP280 measures temperature and atmospheric pressure only; it does not measure humidity.
Altitude readings are estimates calculated from pressure data and can vary with weather and reference pressure.
Confirm the module's operating voltage and logic-level compatibility before connecting it to your controller.
I2C/SPI availability, pin layout, and selectable address depend on the specific breakout board.
