Small Pressure Sensor For Altitude-tracking In Sports & Games

Bosch Sensortec launches smallest high performance barometric pressure sensor at CES2017. Flexible and ideally suited for a wide range of altitude tracking applications.

Bosch unveiled a barometric pressure sensor with a compact size of only 2.0 x 2.0 x 0.75 mm³. The BMP380 is claimed to bring high precision for a wide range of altitude tracking applications including gaming, sports and health management, as well as indoor and outdoor navigation.

“By measuring barometric pressure, the sensor enables drones, smartphones, tablets, wearables and other mobile devices to accurately determine altitude changes, in both indoor and outdoor environments”, the firm touted.

The small package size of only 2.0 x 2.0 x 0.75 mm³ complies with new industry benchmarks and allows the new sensor to be easily integrated into a multitude of existing and upcoming applications and devices.

In drones, the sensor can be used for altitude stabilization to improve their flight stability and landing accuracy. This simplifies drone steering, thereby making drones attractive for a broader range of users.


In wearables and mobile devices, the BMP380 can also substantially improve calorie expenditure measurement accuracy, for example, by identifying whether a person is walking upstairs or downstairs in a step tracking application. Especially in hilly environments, this allows runners and cyclists to significantly improve the monitoring accuracy of their performance, the firm said. In smartphones, tablets and wearables, this sensor brings unprecedented precision to outdoor/indoor navigation and localization applications, i.e. by utilizing altitude data to determine the user’s floor level in a building, and enhancing GPS accuracy outdoors.

The sensor features a built-in FIFO of 512 byte to store pressure and temperature data. The new FIFO and interrupt functionality provide simple access to data and storage. Power consumption is only 2.0µA at 1Hz during full operation.

Covering a wide measurement range from 300 hPA to 1250 hPA, the sensor is claimed to be more accurate than its predecessors. Relative accuracy is +/-0.06 hPa (+/-0.5m) over a temperature range from 25°C to 40°C. Absolute accuracy is between 300 and 1100 hPa is +/- 0.5 hPa over a temperature range from 0°C to 65°C.

“We are very excited about the opportunities that this sensor opens up for designers to further advance their products,” says Jeanne Forget, Vice President Global Marketing at Bosch Sensortec. “Our product is unmatched in its scope, precision and footprint, and provides an improvement for outdoor localization, thereby reducing our reliance on GPS signals”.

The firm said that the sensor will be available for selected customers with the start of channel promotion in the 2nd quarter of 2017.
