AHRS “Attitude and Heading Reference System” for Adafruit’s 9-DOF/10-DOF Breakout

Sensors Rabbit10Dof

AHRS for Adafruit’s 9-DOF/10-DOF Breakout @ The Adafruit Learning System.

AHRS is an acronym for Attitude and Heading Reference System, a system generally used for aircraft of any sort to determine heading, pitch, roll, altitude etc.

A basic IMU (Intertial Measurement Unit) generally provides raw sensor data, whereas an AHRS takes this data one step further, converting it into heading or direction in degrees, converting the raw altitude data into standard units like feet or meters, etc.

To help you get started designing your own AHRS system, or just tp help convert raw sensor data into useful numbers that you can relate to the real world, we’ve created a sample AHRS sketch for the Adafruit 10-DOF IMU and Adafruit 9-DOF IMU breakouts.
