Bosch Sensortec introduces the BMP581, a barometric pressure sensor that couples low power consumption with extreme accuracy to provide altitude tracking in wearables, hearables or IoT devices. This capability makes it ideal for applications such as fitness tracking, fall detection, indoor localization and navigation, enabling new use cases that were previously impossible.
"Building on the excellent performance and low power consumption of previous generations of Bosch sensors, our new BMP581 now delivers an entirely new level of accuracy", says Dr. Stefan Finkbeiner, CEO at Bosch Sensortec. "It’s breathtakingly accurate: it can measure a barometric pressure fluctuation that's equivalent to one-thousandth of the weight of a mosquito (7.6 μg)."
This extreme level of accuracy enables the sensor to detect an altitude change of just a few centimeters. It can, therefore, monitor movement in fitness applications down to the level of individual pull-ups or push-ups, and can provide highly accurate location information for indoor localization, navigation, and floor detection to provide key data for emergency call requirements (E-911).
The sensor can noticeably improve flight stability and landing accuracy in drones, and help detect water levels in household appliances to avoid flooding.
