Adafruit BMP280 I2C or SPI Barometric Pressure & Altitude Sensor

Bosch's BMP280 sensor delivers exceptional environmental monitoring capabilities, offering precise measurements of temperature and barometric pressure. With ±1 hPa absolute accuracy for pressure and ±1.0°C accuracy for temperature, it stands as a leading low-cost option for precision sensing applications.

The sensor's robust feature set includes the ability to function as an altimeter, achieving ±1 meter accuracy by capitalizing on pressure-based altitude changes. Its low altitude noise of 0.25 meters ensures reliable performance, particularly suited for weather sensing projects.

Built for flexibility, the BMP280 supports both I2C and SPI communication protocols. Opt for I2C for straightforward wiring or SPI to avoid address collisions in multi-sensor setups. The sensor comes pre-mounted on a PCB with an integrated 3.3V regulator and level shifting, ensuring compatibility with both 3V and 5V logic microcontrollers.

To facilitate rapid deployment, Bosch provides comprehensive resources including tutorials, wiring diagrams, schematics, libraries, and practical examples. Each order includes a fully assembled and tested PCB breakout with attached headers, equipping you to begin your project seamlessly in under ten minutes.
