Overview

WIth the LSM9DS1 9-axis motion sensor module, your inventions can measure their direction, orientation, and motion.  The LSM9DS1 is used on our ELEV-8 v3 Quadcopter's Flight Controller. We have made it available in a convenient SIP module for easy prototyping, as well as conveniently studying the physics involved in motion tracking.

This sensor is a “system-on-a-chip” that contains 4 different sensors: a 3-axis accelerometer (for measuring gravity or acceleration in 3D space), a 3-axis gyroscope (for measuring rotation), a 3-axis magnetometer (for measuring magnetic field strength - used to find Magnetic North), and a temperature sensor that can be used for calibration.

The LSM9DS1 9-axis motion sensor module can be used with nearly any microcontroller—it can be powered by 2.8, 3.3 or 5 volts and it uses either a 3-pin SPI interface or an I2C bus.  Use it as a single sensor—accelerometer, a gyroscope, a magnetometer, or a temperature sensor—or all of the measurements can be read together for use in inertial measurement or dead-reckoning applications.  It can also be configured to drive an interrupt when detecting impacts, free-fall, or magnetic field ranges.

This module is supported by the Propeller C library lsm9ds1.h, and by a set of code blocks in the BlocklyProp online programming tool.

Features

  • Measures linear acceleration, angular velocity, and magnetic field strength on three axes
  • Measures the temperature, and internally temperature compensates all readings
  • Low power usage—great for battery-powered applications
  • 16-bit precision with selectable sensitivity is adaptable to your project's needs
  • Breadboard-friendly SIP form factor

Application Ideas

  • Physics studies
  • Stalled, tilt, and collision sensing
  • Free-fall detection
  • UAV control systems
  • Platform level/balance
  • Compass navigation
  • Gesture-based game-controller

Note: Though not a drop-in replacement for the discontinued MMA7455 3-Axis accelerometer (#28526) or HMC5883L compass (#29133), this module can be used similarly in applications.
