    BMP388

    The BMP388 is a very small, low-power and low-noise 24 bit absolute barometric pressure sensor. It enables accurate altitude tracking and is specifically suited for drone applications. The best-in-class TCO of the BMP388 between 0-65°C for accurate altitude measurement over a wide temperature range greatly enhances the drone flying experience by making accurate steering easier.

    It is compatible for use with other Bosch sensors, including BMI088 for better performance, robustness and stability.

    The BMP388 sensor offers outstanding design flexibility, providing a single package solution that is easy to integrate into other existing and upcoming devices such as smart homes, industrial products and wearables.

    It is more accurate than its predecessors, covering a wide measurement range from 300 hPa to 1250 hPa. BMP388 exhibits an attractive price-performance ratio coupled with low power consumption. It is available in a compact 10-pin 2.0 x 2.0 x 0.75 mm³ LGA package with metal lid.

    Applications

    • Altitude stabilization in drones
    • Improve calorie expenditure measurement accuracy in wearables for sports and health management
    • Unprecedented precision to outdoor/indoor navigation and localization applications, e.g. in Smart Homes
    • Enhancing GPS accuracy outdoors

     
     

    Drone Applications

    The BMP388 delivers outstanding altitude stabilization in drones, where accurate measurement of barometric pressure provides the essential altitude data for improving flight stability and landing accuracy. The new barometric pressure sensor is part of Bosch Sensortec’s comprehensive sensor solution for drones, which includes the BMI088 Inertial Measurement Unit (IMU) for accurate steering and the BMM150 geomagnetic sensor for the provision of heading data.
