Senses acceleration (or deceleration) and inclination in two dimensions simultaneously. For the acceleration sensing part, attach it to Whirling Dervishes, kinetic sculptures or Fido as he chases the neighborhood cat. It's a visually exciting sensor ! Can be held in the palm of your hand. For the tilt sensing function, attach this sensor to your head to find out if you still can walk straight saturday night at 4 am (or whether you're actually balancing on your head) ! Detects upto ±2 G acceleration and a full 360° in two tilt axes.

| Acceleration application notes |
- With the cables facing yourself, the left cable is output 1 and the right cable is output 2.
- Output 1 corresponds with acceleration perpendicular to the long side of the sensor, while output 2 corresponds with acceleration in the direction of the long side of the sensor.
- Rotating the sensor around either of the two sensitive axes will change the 0 G output value corresponding to the inclination or tilt of the sensor, see inclination application notes.
- Warning ! Make sure the sensor is plugged into the Digitizer with the red wire connected to power. Reversing the plug may cause damage to the sensor.

| Inclination application notes |
- With the cables facing yourself, the left cable is output 1 and the right cable is output 2.
- Output 1 corresponds with inclination perpendicular to the long side of the sensor (ie. rotation about the long side of the sensor), while output 2 corresponds with inclination in the direction of the long side of the sensor (ie. rotation about the short side of the sensor).
- Motion other than rotation (as a result of inclination or tilt) in either of the two sensitive axes may generate sensor output corresponding to the acceleration of the motion, see acceleration application notes.
- Warning ! Make sure the sensor is plugged into the Digitizer with the red wire connected to power. Reversing the plug may cause damage to the sensor.
