BMP280 Barometric Pressure Sensor

By Bosch Sensortec 81

BMP280 Barometric Pressure Sensor

Bosch’s 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. 

The same as its predecessor, BMP180, BMP280 is based on Bosch’s proven piezoresistive 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.

The Bosch Sensortec BMP280 shuttle-board is a PCB with a BMP280 sensor mounted on it. It allows easy access to the sensors pins via a simple socket. As all Bosch Sensortec sensor shuttle boards have identical footprint, they can be plugged into Bosch Sensortec’s advanced development tools (e.g. the Development Board). Of course, the BMP280 shuttle board can also be used for customer’s own implementations.
