BMP280 Pressure & Altitude Sensor Breakout

Measure atmospheric pressure, altitude, and temperature with confidence using the BMP280 Temperature & Altitude Sensor Breakout. Built around Bosch Sensortec’s proven BMP280 sensor, this breakout delivers reliable performance, low power consumption, and excellent accuracy for a wide range of embedded applications. With a simple I2C interface, dual Qwiic connectors, and standard header pins, it integrates effortlessly into Arduino, ESP32, RP2040, and other microcontroller-based projects.

The BMP280 operates over a pressure range of 300 hPa to 1100 hPa, making it well suited for altitude estimation, weather monitoring, indoor navigation, and environmental sensing. It offers a relative pressure accuracy of ±0.12 hPa, corresponding to approximately ±1 meter altitude resolution, and supports configurable oversampling and an internal IIR filter to reduce noise from short-term pressure fluctuations such as airflow or movement. Temperature measurements are provided alongside pressure data, allowing for accurate compensation and stable long-term readings.

This breakout board is designed for flexibility and ease of use. It features two Qwiic connectors for solder-free daisy-chaining, clearly labeled I2C header pins, and a dedicated interrupt pin for data-ready signaling or advanced low-power operation. Thanks to its ultra-low current consumption — as low as 2.7 µA at 1 Hz sampling — the BMP280 breakout is an excellent choice for battery-powered devices, portable sensors, and always-on monitoring systems where efficiency matters.
