LEGO® Tilt sensor
LEGO® Tilt sensor for SBrick Plus
The tilt sensor (part 9584) detects changes in position. It can detect six different positions: tilt this way, tilt that way, tilt up, tilt down, no tilt and any tilt. On occasion, the vibration of the motor will interfere with the accuracy of the tilt sensor. The fix for this is to design a construction in which the motor vibrations are isolated from the sensor.
