GForce2D-18 v1.0 (obsolete)

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 18 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. See this videoclip for a demo of the (2 G) GForce2D-2 acceleration sensing capabilities and this videoclip for a demo of its tilt sensing capabilities !

Similar sensors are:

Application examples

  1. 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).
  2. A wireless Wi-microSystem is recommended in all cases to operate without tether.

Technical specifications

Product GForce2D-18 sensor
Version 1.0 (2007)
Sensing parameter dual-axis acceleration/deceleration
Sensing method MEMS
Bandwidth 50 Hz
Cross-axis sensitivity 2 %
Acceleration resolution 2 mG (at 50 Hz vibration)
Acceleration range 18 G
Acceleration calibration (output 1 or 2)
G Voltage (use 5 V power supply) 7-bit MIDI value (use 'no processing' editor preset)
-18 0.00 0
0 2.52 64
+18 5.0 127
Acceleration application notes
  1. Identify output 1 by it's only pin and output 2 by it's three pins in a row.
  2. Output 1 corresponds with acceleration in the direction of the cable, while output 2 corresponds with acceleration perpendicular to the cable.
  3. Rotating the sensor slowly 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.
  4. 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 range -180 to +180
Inclination calibration (output 1 or 2)
Degrees Voltage (use 5 V power supply) 7-bit MIDI value (use 'no processing' editor preset)
-90 2.17 55
0 2.52 64
+90 2.87 73
Inclination application notes
  1. Identify output 1 by it's only pin and output 2 by it's three pins in a row.
  2. Output 1 corresponds to inclination in the direction of the cable, while output 2 corresponds to inclination perpendicular to the direction of the cable.
  3. 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.
  4. 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.
Power supply 2.4 to 5.25 V DC, 1 mA
Operating temperature -20 to 70 C (-4 to 158 F)
Sensor dimensions 18 x 18 x 5 mm (0.70 x 0.70 x 0.2 inch)
Weight 25 g (0.9 oz), incl. cable
Cable 1.0 m (39 inch), shielded, red wire = power, black wire = ground, grey wire = sensor output 1, white wire = sensor output 2, maximum extension 30 m (98 ft)
Connector double male plug with 3+1 pins in two rows spaced 2.54 mm (0.100 inch)
