Collect and analyze real-world motion data
The CBR 2 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
Plug the CBR 2 sonic motion detector to your TI-84 Plus family calculator using the USB CBR-to-calculator cable and begin collecting data immediately (Vernier EasyData™ App required). The calculator will automatically launch the App and begin displaying the current distance reading. Also, select from several easy-to-use built in activities.

CBR 2 sonic motion detector capabilities and highlights:

• Includes 5 sample classroom activities for math and science
• Pivoting sensor head for easy positioning
• Upgraded design and new color
• USB connectivity to the TI-84 Plus family of graphing calculators
• Record data from 15 cm (5.9 in.) to 6 m (19.7 ft.)
