The AbsoluteIMU-ACG contains three built in sensors which are accelerometer, compass and gyroscope, . The AbsoluteIMU-ACG is compatible with multiple platforms including:
-Mindsensors EVShield (Arduino)
-Mindsensors PiStorms(Raspberry Pi)
The AbsoluteIMU-ACG, has three major sensors First one being an accelerometer, which can be used to measure tilt, detect an impact, measure centrifugal force, and numerous other possibilities.
Second major sensor is the compass, which an be used for many things other than simpy just a compass. For example you can use this sensor to create a metal detection device.
Third, would be the gyroscope, this sensor alone can provide your robot or project with lots of possibilities. You could use the gyroscope to create a self balancing robot(segway). Or create a vibration detection system, aswell as lots of other options.

Do I need to calibrate my AbsoluteIMU-ACG or does it come with a factory calibration?
The AbsoluteIMU-ACG comes with a factory calibration however, given the magnetic field in your location may be more or less than the one at the manufacturing facility so re-calibrating the compass maybe important.
