The pressure sensors in mobile phones and accessories can be used in various use cases, such as to improve the activity
recognition tasks, ambient pressure monitoring, emergency E911 enablement, and automatic airplane mode.
PRESSURE SENSORS
The ST absolute digital output barometer integrates the consolidated pressure sensor in the new fully molded package to
further improve robustness, reliability, and moisture resistance, while reducing package thickness.
Waterproof pressure sensors are also available in the ST pressure sensor portfolio. They are resistant to chemicals like
chlorine, bromine, and salt water, as well as soaps and detergents. The LPS28DFW is an ultracompact piezoresistive
waterproof pressure sensor, which functions as a digital output barometer. Thanks to the dual fullscale (FS) mode, the device
provides wide coverage of both altimeter and water depth (up to 30 meters).
Another winning feature of the LPS28DFW is its lower power consumption and lower RMS noise. The LPS28DFW is the right
pressure sensor for delivering the high level of functionality users want and expect in personal electronics and consumer
applications.
