Motion Detectors

Our motion detectors ultrasonically measure distance to the closest object and create real-time motion graphs of position, velocity and acceleration. Motion is illustrated graphically, making it easy for students to experience the way real scientists collect data. All three models can measure objects as close as 15 cm and include a sensitivity switch making them the perfect complement to our Vernier Dynamics Track.

Do you want to collect motion data using a computer without the interface? The Go! Motion plugs directly into the USB port of your Mac or PC. The included Logger Lite software is ideal for elementary, middle school, and beyond.

For current users of LabPro or CBL 2 interfaces, we recommend the Vernier Motion Detector 2. This motion detector comes with everything you need to connect to your LabPro or CBL 2.

Are graphing calculators your favorite tool to collect data? If so, we recommend the CBR 2 by Texas Instruments. This motion detector comes with everything you need to connect to most TI graphing calculators. Unlike older models, the CBR 2 can connect to a TI-84 Plus or TI-84 Plus Silver Edition through the USB port on the calculator.

Which Motion Detector is Best for Me?

Go! Motion

The Go! Motion is perfect for K-8 science classrooms studying motion. It is the most versatile because it works as a stand-alone unit or with an interface.

Motion Detector 2

We kept the price the same as our older model, but improved the sensitivity and made it possible to detect objects as close as 15 centimeters.

CBR 2

Texas Instruments CBR 2 connects directly to TI graphing calculators to collect motion data.
