Summary

The STMicroelectronics LSM6DS3 Accelerometer Gyroscope component provides 6-axis motion tracking with advanced features including pedometer, tap detection, and free-fall detection. It communicates using the I2C interface and outputs comprehensive motion data.

Description

The LSM6DS3 is a high-performance 6-axis inertial measurement unit (IMU) that combines a 3-axis accelerometer and 3-axis gyroscope with embedded pedometer, tap detection, and free-fall detection capabilities. It features programmable digital filters, configurable full-scale ranges, and intelligent interrupt generation. The sensor provides low-power operation with high accuracy, making it suitable for applications such as wearable devices, activity tracking, gesture recognition, and impact detection systems.
