1. A device, comprising:
a pressure sensor configured to measure pressure in a surrounding environment of the device, and generate a pressure signal indicating the measured pressure;
an inertial measurement unit configured to:
receive the pressure signal from the pressure sensor;
measure accelerations of the device along a plurality of axes;
generate acceleration signals indicating the measured acceleration; and
perform fall detection based on the pressure signal and the acceleration signals to detect a fall event; and
an application processor configured to be notified of the fall event by the inertial measurement unit, the inertial measurement unit communicatively coupled between the pressure sensor and the application processor.
