2.1

Pedometer functions: step detector and step counters

The LSM6DSV80X embeds an advanced pedometer with an algorithm running in an ultralow-power domain in

order to ensure extensive battery life in battery-constrained applications.

Leveraging enhanced configurability, the advanced embedded pedometer is suitable for a large range of

applications from mobile to wearable devices.

The algorithm processes and analyzes the accelerometer waveform in order to count the user's steps during

walking and running activities.

The pedometer works at 30 Hz and it is not affected by the selected device power mode (ultralow-power, low-

power, high-performance), thus guaranteeing an ultralow-power experience and extreme flexibility in conjunction

with other device functionalities.

The pedometer output can be batched in the device's FIFO buffer, in order to decrease overall system supply

current.

ST freely provides the support and the tools for easily configuring the device and tuning the algorithm

configuration for a best-in-class user experience.
