Accelerometer Gyroscope Compass LSM9DS1(I2C)

File:TArduinoLSM9DS1.png

Summary

Integrated 9-DOF inertial measurement unit combining 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer with I2C interface.

Description

The LSM9DS1 component provides comprehensive motion sensing with simultaneous acceleration, angular rate, and magnetic field measurement across three axes. It features programmable full-scale ranges for each sensor, configurable sample rates, digital filtering, and low-power modes. The accelerometer and gyroscope share one I2C address while the magnetometer uses a separate address, enabling independent configuration and operation. Typical applications include orientation detection, motion tracking, navigation systems, and gesture recognition.
