Two sensors for the price of one. Senses acceleration (or deceleration) and inclination (tilt, ie. acceleration due to gravitation) in two dimensions simultaneously.
Detects upto ±2 G acceleration and a full 360° in two tilt axes.
It's a visually exciting sensor ! Can be held in the palm of your hand.
Similar sensors are:
- GForce3D-6 (6 G in 3D)
- GForce3D-35 (35 G in 3D, but cannot measure tilt, ie. acceleration due to gravitation)
Application examples
- See how it was used in dance performance for Tres a la Vez (incl. software).
- Use for hand motion and jolt, jerk or impact detection (attach it to Whirling Dervishes,
kinetic sculptures or Fido as he chases the neighborhood cat).
- The tilt sensing function is great for balance measurement: 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) !
- A wireless Wi-microSystem
is recommended in all cases to operate without tether.

Acceleration application notes |
- Identify output 1 by it's only pin and output 2 by it's three pins in a row.
- Output 1 corresponds with acceleration in the direction of the cable, while output 2 corresponds with acceleration perpendicular to the cable in the plane of the sensor.
- Rotating the sensor around either of the two sensitive axes will change the at-rest 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 |
- Identify output 1 by it's only pin and output 2 by it's three pins in a row.
- Output 1 corresponds to inclination in the direction of the cable (ie. rotation about the cable), while output 2 corresponds to inclination perpendicular to the cable.
- Motion other than rotation (as a result of inclination or tilt) in either of the two sensitive axes will 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.
