Data export

We are currently updating our support articles and some info may be outdated. Read release notes here.

General
#

Exporting data is done via our web application: https://app.sens.dk/

We recommend using an internet browser on a computer. This article explains how to export one or more files:

Furthermore the article contains information about the difference of the available file formats:

Export summarised data, PDF files and raw data by participant profiles
#

It is possible to export data for several participants by only a few clicks. This is possible for summarized data and the visual PDF reports, as well as for raw accelerometer data.

  1. Export your files by entering the “Workspace” menu from the top menu bar. Click the tab “Completed”.
Workspace menu with Completed tab
  1. Click “Bulk export” and select the participants you wish to export data for. Select all participants by selecting the top check box, or click the participants you want to export.
Bulk export participant selection

  1. Click the green “Export selected” button.

  2. Select the preferred file format (Activity data - CSV, PDF, or raw accelerometer data - Binary). Read more about the available file formats below.

File format selection

You can now download your files from the “Files” tab.

Activity data - summarised CSV format
#

You have the following options for exporting CSV files:

CSV export options

“1 hour”, “15 min” and “Detailed” contain data for all activitiy categories. Select the degree of detail that best suits your data processing needs.

Note: Beware that data can only be exported if you have entered a specific start- and end date for the participant. See how to define the export period here.

Activity data - visual PDF reports
#

PDF reports give a quick and easy overview of the monitoring period. Note that a maximum of 14 days can be included in the report.

You have the following options for PDF reports:

PDF export options

“Week overview” includes a detailed view of each day in the monitor period like what you see in the web app.

The “Average” includes a summary of the monitor period with average activity per day, a pie chart and a bar chart.

“Combined” is a combination of the “Week overview” and “Average”.

Note: It is possible to create a PDF report for a maximum of 14 days due to the large amount of data.

Raw accelerometer data in BIN/HEX or CSV format
#

“Accelerometer Data” contains a BIN-file with raw accelerometer data. When you export from the Workspace tab, you will export the data by participant profile.

Accelerometer data export option

Binary format is compact and can be parsed in Python, R or similar.

The format is:

  • 6 bytes = Unix timestamp in ms
  • 2 bytes = X, signed 16 bit integer x 0.0078125 G
  • 2 bytes = Y, signed 16 bit integer x 0.0078125 G
  • 2 bytes = Z, signed 16 bit integer x 0.0078125 G

Range: -4G to +4G, 10 bit resolution

Example:

  • 016C87D85F170022FFD9FFAC
  • 016C87D85F6E0022FFD9FFAC
  • 016C87D85FC50022FFD9FFAC
