Digital, Barometric Pressure Sensor, 300 - 1100 hPa, 2.0 x 2.5 x 0.95 mm

Manufacturer's part number :


Manufacturer Bosch Sensortec

Bosch Sensortec

Description :

The 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 driven devices such as mobile phones, GPS modules or watches.

The BMP280 is perfectly suitable for applications like floor level detection since the sensors features excellent relative accuracy of ±0.12 hPa, which is equivalent to ±1 m difference in altitude, and an offset temperature coefficient (TCO) of only 1.5 Pa/K (equivalent to 12.6cm/K).
