VibSensor is a vibration meter geared to science and engineering applications where quantitative accelerometer and vibration data are needed. It turns your mobile device into a vibrometer or seismometer, with easy collection, data storage, and email of data. VibSensor gives the user five tools: Live Display: See tilt and vibration data in real time. Acquisition: Timed or vibration activated acquisition, with settable delay, duration, and trigger level. Collect raw accelerometer data for up to 10 minutes at max rate allowed by device. Also analyze low frequency vibrations with periods up to five minutes. Data Storage: Acquired collections are stored on the device, with date and time stamp for later retrieval. Collections can be named for easy identification. Analysis: Each collection can be viewed to see the raw accelerometer data, processed tilt and vibration, and calculated power spectral densities, both in graphical and report format. Units can be selected to be either g or m^2/sec. Email Access: Users can email raw or processed data in text (csv or tab-delimited) or MATLAB format. With VibSensor, you can explore the world of vibrations. Capture vibrational resonances and magnitudes, or even use it like a seismograph to capture an earthquake!
