HiTechnic NXT Angle Sensor

Call for price

Measure axle rotation position and rotation speed with the HiTechnic Angle Sensor.


The HiTechnic Angle Sensor connects to a standard LEGO Technic cross axle and measures three rotation propertied of an axle. These are

  • Absolute Angle: the rotation angle of an axle from 0 degrees to 359 degrees, accurate to 1 degree.
  • Accumulated Angle: the accumulated multiple rotation angle measured since the last reset function was performed.
  • Revolutions per Minute (RPM): the current estimate of rotation rate from 1 RPM up to 1,000 RPM.

The Angle sensor is ideal for building into complex models where monitoring the shaft angle or location and/or the speed of rotation is desired.

With its very low friction mechanism, the HiTechnic Angle Sensor is ideal for building models where accurate measurement of rotation properties of an axle is key. Perfect for building a distance measuring wheel or a weather station wind vane.
