BMP280 Breakout Board  I2C or SPI Barometric Pressure & Altitude Sensor

The Bosch BMP280 chip incorporates two sensors: a Barometric pressure sensor and an other one for temperature. this cheap but accurate sensor is perfect for all weather applications thanks to the ± 1hPa / ± 1 ° C accuracy. With the barometer, this sensor can also be used as an altimeter with an accuracy of ± 1 meter. This sensor is also very versatile thanks to its I2C and SPI communication bus

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.

As its predecessor BMP180, 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. Numerous device operation options offer highest flexibility to optimize the device regarding power consumption, resolution and filter performance. A tested set of default settings for example use case is provided to the developer in order to make design-in as easy as possible.
