This CAN based IMU with an inbuilt Attitude Heading Reference System (AHRS) outputs:
- 3 axes of acceleration
- 3 axes of rotation
- 3 axes of magnetic field flux
- Quaternion angles
- Euler angles (pitch, roll and yaw/bearing)
The difference between an IMU and an AHRS sensor is that the AHRS uses a magnetometer and thus the yaw/bearing is relative to magnetic north.
The configurable CAN interface allows the unit to attach to any vehicle with a CAN bus.
For example, this sensor can be used to analyse vehicle motion allowing users to gain a greater understanding of vehicle dynamics. Vibration analysis is another application example.
An example of how the yaw data can be used is shown in one of our latest projects: Determination of Rally Car Side Slip.
Wide ranging input voltage and the small size and mass of the unit allows easy interface into most vehicles.
