Goniometer Sensor – PASPORT

Product Code: PS-2137


The PASPORT Goniometer Sensor allows students to use their own bodies to contextualize physics. The Goniometer can be connected to knee, hip, or elbow joints to measure angle changes throughout a variety of movements. It can be used to measure the angular position, velocity, and acceleration of an arm or leg.

The PS-2137 includes one Angle Sensor (PS-2139) and one Goniometer Probe with a Velcro connection kit. An add-on Goniometer Probe (PS-2138) must be purchased to measure the motion of two joints simultaneously.

Developed in cooperation with Nancy Beverly, Associate Professor of Physics at Mercy College, Dobbs Ferry, New York.


  • Angular Motion: Measure the angular position, velocity, and acceleration of an arm or leg
  • Tangential Velocity: Simply enter the correct radius and our software will calculate the linear velocity for any point on an arm or leg
  • Torque and Power: Use with a Force Sensor to measure the power generated by an arm or leg lifting an object. PASCO software can be used to integrate the power vs. time graph to determine energy consumption.
