Mouser is stocking Bosch’s BMP390 barometric pressure sensor. The product is described as an ultra-small, low-power and low-noise 24-bit absolute barometric pressure sensor with vertical (z-axis) capabilities that enable accurate indoor localization with smartphones in case of emergencies.
The sensor offers a pressure range of 300hPa to 1250hPa at zero to 65°C with typical relative accuracy of ±0.03hPa. Power consumption is 3.2µA at 1Hz and the 2.0 by 2.0 by 0.75mm form factor suits altitude-tracking applications in smartphone and wearable devices. Through its vertical-specific position capabilities and accuracy, the sensor helps mobile phone designers meet upcoming FCC requirements for location accuracy.
The BMP390 enhances design flexibility, allowing easy integration into existing and developing applications, including Internet of Things devices, smartphones, GPS modules, wearables, hearables and drones.
