Use case and configuration example for the
LPS25HB
Based on these three main device settings, in order to make simpler the sensor use in the
application context, some recommendations are provided, as a guidelines for different
applications in the domain of portable device (PD) such as smartphone or wearable, of
weather stations for applications like barometric pressure measurement, or more in
general, of elevator and floor change detection functions, drop detection and indoor
navigation as well.

In the column ”Device mode description”, the recommended configurations when the
device is working in FIFO MEAN MODE are provided, as a combination of FIFO length,
temperature and pressure oversampling for optimizing the noise figure accordingly to the
selected “use case". An appropriate ODR setting is suggested to optimize the
corresponding power consumption.
Of course, together with the suggested use cases, different configurations can be chosen,
in terms of oversampling, ODR and FIFO coefficients, to better match the specific
application scenario.
