Bosch BMP390 air pressure sensor to improve indoor navigation in emergency

     Bosch BMP390 air pressure sensor. This is a super small, low-power, low-noise 24 bit absolute air pressure sensor with vertical (z-axis) function, which can be used for accurate indoor positioning through smart phones in an emergency.

     The Bosch BMP390 air pressure sensor has a pressure range of 300hPa to 1250hPa at 0 ° C to 65 ° C, and a typical relative accuracy of ± 0.03hPa. The power consumption of the sensor at 1Hz is only 3.2 µ A, and its overall dimension is only 2.0mm × 2.0mm × 0.75 mm, which is very suitable for various low power consumption altitude tracking applications in smartphones and wearables. With its vertical orientation specific positioning capability and excellent accuracy, the BMP390 sensor can help mobile phone designers meet the positioning accuracy requirements coming from FCC.

     For development purposes, Trader also has BMP390 Shuttle Board and Application Board 3.0 in stock. These are two development boards designed to be used together. Developers can use them to access the pins of the BMP390 sensor for evaluation, and build prototypes to test the use cases.

     As a compact single package solution, BMP390 can enhance the flexibility of design, and can be easily integrated into many existing and developing applications, including Internet of Things (IoT) devices, smart phones, GPS modules, wearables, smart headphones and drones.
