BMP280 sensor API

This package contains BMP280 sensor API

Sensor Overview

BMP280 is an absolute barometric pressure sensor especially designed for mobile applications.The sensor module is housed in an extremely compact package. Its small dimensions and its low power consumption allow for the implementation in battery powered devices such as mobile phones, GPS modules or watches. BMP280 is based on Bosch's proven Piezo-resistive pressure sensor technology featuring high accuracy and linearity as well as long term stability and high EMC robustness.

Key features

  • Operation range (full accuracy) : Pressure: 300...1100 hPa. Temperature: -40 .... +85 degrees C .

  • Absolute accuracy(Temp. @ 0 ..... +65 degrees C) : ~ +/- 1 hPa

  • Relative accuracy (p = 700…900hPa, Temp. @ +25 .... +40 degrees C): +/-0.12 hPa (typical) equivalent to ±1 m.
