USB Plug and Collect

The CBR™ 2 motion sensor plugs into TI-Nspire™ CX II and TI-84 Plus families of graphing calculators using the USB CBR-to-calculator cable. Using the CBR™ 2 system and the Vernier DataQuest™ App for TI-Nspire™ technology, students can kinesthetically explore motion and graphing with the Motion Match feature.

TI-Nspire™ CX II graphing calculator family


Using the CBR™ 2 system and the Vernier DataQuest™ App for TI-Nspire™ technology, students can kinesthetically explore motion and graphing with the Motion Match feature.

They simply plug in the CBR™ 2 device and watch the Vernier DataQuest® App launch automatically. Once they choose Motion Match, challenge your students to match the graph by walking back and forth using the CBR™ 2 device. Students enjoy changing their position and speed as they attempt to get the perfect match.

TI-84 Plus CE graphing calculator family

single-sensor-Walk-the-Graph-without-avatar_HH2 Students can also begin collecting data immediately using their TI-84 Plus graphing family calculator using the Vernier EasyData® App. The calculator will automatically launch the app and begin displaying the current distance reading. Also select from several easy-to-use activities that are built in.
