The CBR 2 motion sensor is TI's answer to an easy; affordable data collection device! Designed for teachers who want their students to collect and analyze real-world motion data; such as distance; velocity and acceleration. Great for algebra through calculus and statistics; physical science and physics.

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. Using the CBR 2 and the newest TI-Nspire application; Vernier DataQuest; students can kinesthetically explore motion and graphing with the "Motion Match" feature. They simply plug in the CBR 2 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 motion detector. 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.

Pivoting sensor head

Simply point the sensor where the action is! It will measure distance; velocity and acceleration - up to 200 samples per second!
