Example Applications using Accelerometers
Helmholtz Resonator
This simple experiment uses a 2-liter bottle and an X6-2 accelerometer to demonstrate Helmholtz's equation for a resonating a cavity. The test procedure is then applied to a subwoofer speaker to determine the enclosure resonance frequency and speaker performance.
Pendulum Experiment
So much has changed over the years. Has the gravataional constant, or the mass of the earth changed the local gravitational field lately? We decided to perform this simple pendulum experiment and find out.

Calculating the Acceleration of Gravity Using an Accelerometer Data Logger.pdf)Package Monitoring
Ever wonder when and where your shipment was damaged? The USB Accelerometer can record the movements of a package during shipment and record with precise time when an impact occurred. See how the USPS shipped a USB Accelerometer from Bay St. Louis, MS to Huntsville, AL.
Vibration Analysis
Here, an X6-2 is used to compare the vibration characteristics of two residential sized central air conditioners and illustrate the propagation of the vibration through the walls.
Actigraphy
Ever wonder how much standing, sitting, and walking occurs during a typical day at Walt Disney World? Using a GCDC USB Accelerometer device, data was collected and analyzed to provide a graphical representation of activity at a theme park. Also, see the acceleration characteristics of several popular rides at Walt Disney World. Read about it all here. Then, continue on to read about experiences at Universal Studios Orlando.
The data logging capabilities of the X6-1 and X6-2 allow unique “finger printing” of human activities, such as walking, running and house chores.
Roller Coasters
See the dizzying acceleration of many popular rides at Wald Disney World and Universal Studios Orlando.
Impact Study
An X250-1 impact sensor is used to show the acceleration, flight, and impact of an arrow.
RC Airplane Flight Dynamics
The unfortunate demise of an RC airplane is recorded with an X6-2 accelerometer.
Impact Force of a Soccer Ball
See the force felt when a soccer ball bounces off an athlete's head.
Example Applications using a Barometer
Kite Altitude
Strap a B1100-1 barometric pressure data logger to a kite and see how high a kite flies.
Elevator Monitoring
Monitor the altitude and ascension rate of an elevator while listening to soft soothing instrumental re-mixes of pop-music.
RC Airplane Altitude
See an RC airplane sore to 430 feet, perform loops, and a final power-dive into an awaiting oak tree. Post-crash analysis is compiled using synchronized data collected by the B1100-1 and X6-2 data loggers.
Pressure Profile for a Car
We drove a 2008 Honda Civic down the highway to see how the aerodynamics of the vehicle affected the pressure on different areas of the car.
