by HiTechnic Nxt Acceleration/Tilt Sensor For Lego Mindstorms  (Multicolor)

Now you can make robots that know which way is up! The HiTechnic Accelerometer / Tilt Sensor measures acceleration in three axes. It also measures tilt along each axis. Using the sensor, you can measure the acceleration of your robot build robots in the range -2g to + 2g. Great for experimenting with acceleration forces in cars, on amusement rides, even on swing sets. This sensor will also tell you if your robot is level so you can build self-leveling robots and much more.
