Wireless Dynamics Sensor System
(Order Code WDSS)
The Wireless Dynamics Sensor System (WDSS) allows you to take data from a
three-axis accelerometer, force sensor, and altimeter, using a Bluetooth
®
wireless
connection to your computer. It is the perfect tool for dozens of physics and physical
science experiments such as:
•
Studying the motion of a dynamics cart on a track. The WDSS can be mounted
on a cart, avoiding the problems associated with wires when using conventional
accelerometers and force sensors.
•
Amusement park and playground rides. The WDSS has internal memory and can
collect acceleration and altitude data (to get a profile of the ride) for over 100,000
readings over several minutes. You can store multiple runs before retrieving the
data.
•
Studying simple harmonic motion by mounting the WDSS as an oscillating mass
hanging from a spring.
•
Studying accelerations of skateboarders or dancers with a WDSS mounted on
them while data are recorded on a nearby computer.
•
Studying forces and accelerations during circular motion by mounting the WDSS
on a turntable or bicycle wheel.
In addition, you can use the WDSS to do other traditional experiments that you do
with conventional accelerometers and force sensors. You will find more information
on experiments you can do with the WDSS later in this manual.

The WDSS hardware
The photo below shows the Wireless Dynamics Sensor System with the key parts
identified.
•
On/Off
Switch:
The switch controls the power to the WDSS. Turn the switch off
when you are not using the WDSS. Data stored in the WDSS memory will not be
lost when you turn off the power.
•
Battery Charging LED:
This yellow LED indicates when the WDSS batteries
are being charged. The LED will come on as soon as the WDSS is plugged in
unless the battery is already 100% charged. The LED will go off when the battery
becomes fully charged.
•
Power
Connector
: This connector is used with a 6 V DC, center-negative power
supply, like the one included with the WDSS or with a Vernier LabPro interface.
This power supply is Vernier order code IPS.
