BMP280 pressure sensor is designed for mobile applications.The sensor module is to use a very compact package.Its small size and low power consumption to allow the battery power supply devices such as mobile phone, GPS module, or a watch.
BMP280 proven piezoresistive pressure sensor technology has high precision, high linearity and long-term stability and robustness of electromagnetic compatibility.Many devices operating option provides flexibility and optimize the power consumption device, resolution and filter performance.A test example use cases, the default setting is for developers in order to make the design as simple as possible.

GPS navigation enhancement (such as time the improvement of app, navigation calculation, slope detection)
Indoor navigation (ground test, elevator testing)
The application of the navigation of outdoor, leisure and sports
The weather forecast
The application of the health care (such as spirometry)
Vertical speed indicator (such as rising or sinking speed)
Applications such as weather forecast, elevation measurement, indoor navigation, fitness and sports, etc.Digital pressure sensor BMP280 can provide excellent performance, relative accuracy of plus or minus 0 12 hPa (+ / - 1 m).

* precise elevation measurement
Pressure sensors can improve the precision of GPS/GNSS, especially in small number or GPS satellite signal loss.Today, air pressure sensor has become one of the key elements for high-end smartphones differentiation.

Digital pressure sensor BMP280 can provide excellent performance, relative accuracy of + / - 0.12 hPa (plus or minus 1 meter), the power consumption of the sensor is only 2.7 mu A.BMP280 has 2.0 x 2.5 x 2.5 mm3 in small package, including the pressure and temperature measurement function.
