With the robust LSM9DS1 9-axis motion sensor module, your inventions can measure their direction, orientation, and motion. The LSM9DS1 is used on Parallax's ELEV-8 v3 Quadcopter'sFlight Controller. They designed it in a convenient SIP module for easy prototyping, as well as efficiently 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 use 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. (Code and files linked below.)
