CBR™ 2 device capabilities and highlights: Includes five sample classroom activities for math and science Pivoting sensor head for easy positioning (measure distance, velocity and acceleration — up to 50 samples per second) Upgraded design and color USB connectivity to the TI-Nspire™ family of graphing calculators, TI-Nspire™ software, and TI-84 Plus family graphing calculators Record data from 15 cm (5.9 in.) to 6 m (19.7 ft.) Sensitivity switch for normal and track modes Use with dynamic tracks, coffee filters, graph match, ball-toss and other activities Improved real-time graphing Compatible with the following calculators: TI-84 family graphing calculators TI-Nspire™ family of graphing calculators CBR™ 2 system includes: CBR™ 2 sonic motion detector USB CBR™ 2 calculator cable (for use with TI-84 Plus family graphing calculators) Extended length I/O cable, for connecting to calculator input/output port Four AA batteries Guidebook: Getting Started with the CBR™ 2 device USB plug-and-collect The CBR™ 2 motion sensor plugs into TI-Nspire™ 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. 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. Students can also 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. Built-in functionality Pivoting sensor head (0o – 180o) Measures object distance from 0.15 m – 6 m (5.9" – 19.7 ft.)
