Overview of the Sensor Application
This application leverages the internal sensors of your smartphone to collect, display, record, and export data files in .csv format. For more information on case usage in research and development, as well as lesson plans for educators in the fields of science, technology, engineering, and mathematics (STEM), including physics, please visit www.vieyrasoftware.net. Please note that the availability, precision, and accuracy of sensors depend on your smartphone's hardware.

Application Features
- Record: Capture data by pressing the red floating action button. Saved data can be accessed through the folder icon.
- Export: Share data via email or upload to Google Drive or Dropbox. Local files can be transferred from the folder icon.
- Sensor Information: Click the (i) icon to view sensor name, vendor, current data collection rate, and learn about the data collected by each sensor along with its physical operating principle and additional resources.
Settings
Note: Not all settings are available for all sensors.
- Data Display: View data in graphical, digital, or vector form.
- Graph Display: View multi-dimensional data sets on a single shared graph or in multiple individual graphs.
- Displayed Axis: For multi-dimensional data on a single shared graph, select total, x, y, and/or z-axis data.
- CSV Timestamp Format: Record clock time or elapsed time with sensor data.
- Line Width: Adjust the visual presentation of data with Thin, Medium, or Thick lines.
- Sensor Collection Rate: Set collection rate as Fastest, Game, UI, or Normal. The collection rate is displayed for each option when selected.
- Keep the Screen On: Prevent the app from turning off the screen automatically.
- Calibrate: Calibrate selected sensors.
