Texas Instruments CBR2/PWB/11E1/A TI CBR Motion Sensor

Calculator Based Ranger System 2... If you teach math, physical science or physics, you may want to consider the CBR 2. The CBR 2 collects distance, velocity and acceleration data while connected directly to a TI calculator. The connection to the calculator is through the calculator link port or, if you have a TI84 Plus or TI84 Plus Silver Edition, the CBR 2 can connect to the calculator's USB port. When the CBR 2 is connected to the USB port of the TI84 Plus, the EasyData application automatically starts and you are ready to collect data.
