TI-84Plus CE with CBR2

USB Plug and Collect

The CBR 2™ motion detector plugs into TI-Nspire™ learning handhelds and TI-84 Plus family calculators using the USB CBR-to-calculator cable.  The CBR 2™ motion detector can also connect to a computer with the TI-Nspire™  software installed using the USB CBR to computer cable. 

Using the CBR 2™ and the newest TI-Nspire™ application, Vernier DataQuest®, students can kinesthetically explore motion and graphing with the "Motion Match" feature.

Displays in real time

Students can begin collecting data immediately using their TI-84 Plus family calculator (Vernier EasyData® app required). The device will automatically launch the app and begin displaying the current distance reading. Also select from several easy-to-use activities that are already built in.
