Education Technology

Ideal for math and science

The CBR™ 2 sensor is a great tool for students learning algebra, calculus, statistics, physical science and physics.

Flexibility in design

The pivoting head makes it easy to reposition the sensor to capture all the data you need for quick, real-time graphing.

Built for accuracy

Measure distance, velocity and acceleration up to 50 samples per second and record data from 15cm (5.9 inches) to 6m (19.7 feet) away.

Different mode options

A sensitivity switch flips between normal and track modes.

Multiple ways to have fun

Use the sensor with dynamic tracks, coffee filters, graph match, ball toss and other activities.
