The BMP280 barometric pressure sensor is designed for mobile applications. The sensor module uses a very compact package. Its small size and low power consumption allow the realization of devices such as battery-powered mobile phones, GPS modules or watches.

The proven piezoresistive pressure sensor technology of BMP280 has electromagnetic compatibility with high accuracy, linearity, long-term stability and high robustness. Many equipment operation options provide flexibility, optimized power consumption of the device, resolution and filter performance. In the case of a test example used, the default settings are for developers in order to make the design as simple as possible.

application

GPS navigation enhancements (e.g. time advance improvement, dead reckoning, slope detection)

Indoor navigation (ground detection, elevator detection)

Outdoor navigation, leisure and sports applications

Weather forecast

Applications in health care (eg spirometry)

Vertical speed indication (such as ascending or sinking speed)

Application areas such as weather forecast, altitude measurement, indoor navigation, fitness and sports, etc. The digital air pressure sensor BMP280 provides excellent performance with a relative accuracy of ±0 12 hPa (equivalent to ±1 meter).

* Accurate altitude measurement

The barometric pressure sensor can also improve GPS/GNSS accuracy, especially when the number of satellites is small or the GPS signal is lost. Nowadays, the barometric pressure sensor has become a key element in the differentiation of high-end smart phones.

The digital air pressure sensor BMP280 can provide excellent performance, with a relative accuracy of ±0.12 hPa (equivalent to ±1 meter), and the sensor power consumption is only 2.7μA. BMP280 has a small package of 2.0 x 2.5 x 0.95 mm3, including pressure and temperature measurement functions.
