The CBR 2 motion detector connects directly to a Texas Instruments graphing calculator—eliminating the need for an additional data-collection interface.


The CBR 2 collects distance, velocity, and acceleration data while connected directly to a TI graphing calculator, so you don’t need a data-collection interface like CBL 2™ or TI-Nspire™ Lab Cradle. The connection to the calculator is through the calculator link port or, if you have any model TI-84 Plus calculator or TI-Nspire handheld the CBR 2 can connect to the calculator’s USB port.

CBR 2 Key Benefits

  • Use CBR 2 to teach important concepts in physics, physical science, and math.
  • Engage your students with hand-on activities.
  • Study the motion of a ball tossed in the air, or a cart on a ramp.
  • Attach CBR 2 directly to the Vernier Dynamics Track.

Other Important Features Include

  • The measurement range is 0.15 m to 6 m.
  • CBR 2 has a sensitivity switch which lets you customize settings to your experiment.
  • The CBR 2 is built with a pivoting head, making it easy to set up experiments.
