Thank you for purchasing the Smart Wireless Rotary Motion Sensor. We pride ourselves on producing high quality products that meet with the demands of the busy classroom environment. If you have any problems using this sensor, please read this documentation in full before contacting the Data Harvest support team.


The Smart Wireless Rotary Motion Sensor is a multi-range sensor for studies of rotational and periodic motion. It is highly accurate, with an extremely low friction bi-directional position sensor capable of measuring a variety of motions including: - pendulum, angular, rotational, and distance moved by an object.  

The sensor can measure: 

  • Linear displacement using the pulley ranges or optional toothed rack
  • Angular displacement using the angular position or pendulum ranges
  • Angular velocity using the revolutions or radians per second ranges 

The Rotary Motion Sensor is especially good for work with SHM and pendulum work.
