Bosch BMP390 barometric pressure sensor

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

The barometric pressure sensor offers a pressure range of 300 to 1250 hPa at 0 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 x 2 x 0.75 mm form factor, making it suitable for a wide range of low-power, altitude-tracking applications in smartphone and wearable devices. Through its vertical-specific position capabilities, the sensor helps mobile phone designers meet upcoming FCC requirements for location accuracy.

The minuscule, single-package product should enhance 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.
