Adafruit BMP280 I2C or SPI Barometric Pressure & Altitude Sensor

Bosch's BMP280 sensor delivers precise environmental data with advanced temperature and barometric pressure capabilities, offering a significant upgrade over predecessors. It features ±1 hPa absolute accuracy and ±1.0°C temperature accuracy, making it perfect for weather sensing and altimetry, boasting ±1 meter altitude accuracy.

Pressure-altered altitude readings are finely honed with a low altitude noise level of 0.25m, complemented by rapid conversion times. Compatible with both I2C and SPI, it offers flexible integration options. Soldered onto a custom PCB in the STEMMA QT format, it integrates easily into projects, supporting solderless connections and daisy-chaining with other sensors via SparkFun Qwiic connectors.

Optimized for use with 3.3V or 5V systems, it supports platforms like the Metro M4 or Arduino Uno seamlessly. Comprehensive tutorials, including wiring diagrams and example code, simplify project setup, ensuring you can kickstart your applications swiftly.
