A Truly Wireless System

Last year, we introduced a new, low-friction Vernier Dynamics System. This year, we eliminated another source of friction—the wires. With the new Wireless Dynamics Sensor System, your carts will be free to roll wherever the experiment takes them!

All in One. All Wireless.

The Wireless Dynamics Sensor System combines a 3-axis accelerometer, altimeter, and force sensor into one unit that communicates wirelessly with your computer using Bluetooth® wireless technology. You can also use it as a stand-alone data logger. It's more than just a wireless sensor; it's a data-collection system completely free of cables.

A Complete System

The Wireless Dynamics Sensor System includes a high capacity Lithium-Ion rechargeable battery and charger, AAA alkaline battery holder (allows you to use AAA batteries instead of the rechargeable battery), bumpers for collisions, hooks for mounting the unit in different positions, mounting hardware for Vernier and other dynamics carts, and manual.

Wireless Dynamics Sensor System Activities Booklet

Download our booklet that contains six activities using the Vernier Wireless Dynamic Sensor System and Vernier Logger Pro software for collecting, displaying, printing, graphing, and analyzing data. Many of the data-collection features of the WDSS are illustrated in these activities, providing a foundation to explore accelerations, forces and their interrelationships. The activities adapted from teacher training materials created by Chris Butlin, Educational Consultant, York, UK.

Here are the seven labs in the booklet:

1. WDSS Bungee Jumper
2. Centripetal Accelerations on a Model Centrifuge
3. Mission to Titan - Investigating Surface Composition
4. Physics at Amusement Parks
5. Newton's Second Law
6. Newton's Third Law
7. Investigating Collisions with Crumple Zones

Go for a Ride

Let your students experience physics with activities from the Amusement Park Physics! Use data-collection technology to study roller-coaster physics and other amusement park rides. Now you can measure altitude changes and acceleration with the Wireless Dynamics Sensor System, then transfer the data wirelessly to your computer for analysis and comparison. Use a Data Vest to hold the Wireless Dynamics Sensor System in place during the ride.

All Systems Connected

The WDSS can be used alone, with one or more additional WDSS units, or with other interfaces such as a LabPro. The WDSS does not require a LabPro, but it can be used to take data simultaneously with a LabPro or other devices. Here are some common combinations:

• Two WDSS units connected by Bluetooth to a single computer for Newton's Third Law experiments.
• A WDSS used with a LabPro, Motion Detector, and a Dual Range Force Sensor for impulse-momentum experiments.
• A WDSS with a Go! Link and a Dual Range Force Sensor for Newton's Third Law experiments.
• A WDSS, a Go!Motion, and a Vernier Dynamics System create an elegant impulse-momentum experiment setup.

System Requirements

• Logger Pro 3.4.5+ software
  WDSS requires Logger Pro 3.4.5 or above, which is sold separately. If you have any version of Logger Pro 3, you can upgrade to the latest version by downloading the free updater.
