Pressure sensor suits smartphones and wearables

The BMP390 is an ultra-small, low-power and low-noise 24-bit absolute barometric pressure sensor with vertical (z-axis) capabilities that enable accurate indoor localisation with smartphones in case of emergencies.

It offers a pressure range of 300 hPa to 1250 hPa at 0°C to 65°C with typical relative accuracy of ±0.03 hPa.

The sensor features low power consumption of 3.2 µA at 1 Hz and a small 2.0 mm × 2.0 mm × 0.75 mm form factor, making it ideal for a wide range of low-power, altitude-tracking applications in smartphone and wearable devices.

Through its vertical-specific position capabilities and exceptional accuracy, the BMP390 sensor helps mobile phone designers meet upcoming FCC requirements for location accuracy.

For development, Mouser also stocks the BMP390 Shuttle Board and the Application Board 3.0.

Designed to be used together, the Application Board and Shuttle Board enable access to the BMP390 sensor’s pins to allow for evaluation and for building prototypes to test use cases.

The minuscule, single-package BMP390 solution enhances design flexibility to allow easy integration into a multitude of existing and developing applications, including Internet of Things (IoT) devices, smartphones, GPS modules, wearables, hearables and drones.
