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:
- Bulk export - export several CSV or PDF files at once
- Export data in CSV-, BIN or PDF format
- Downloading data to your device
Furthermore the article contains information about the difference of the available file formats. Read more about:
Bulk export - export several CSV or PDF files at once
It is possible to export data for several patients/participants by only a few clicks. This is possible for summarized data and PDF reports, but not for raw accelerometer data. If you wish to export raw accelerometer data, please refer to this section.
1) Export your files by entering the "Patients" menu from the top menu bar.
2) Click "Bulk export"
3) Select the participants you wish to export data for. Select all participants in a project by ticking the top check box.
4) Click the green "Export selected" button when you have selected all the participants you wish to export.
5) Select the preferred file format. Read more about the available file formats in this article.
You can now download your files from the "Files" modal.
Export data in CSV or PDF format
If you wish to export several files, which are not raw accelerometer data, we suggest using the "Bulk export" function. Find the guide in the beginning of this article: Bulk export - export several files at once
1) Export your files by entering the "Patients" menu which you access via the top menu bar.
2) Click the three dots on the right and select "Export data".
3) Select the preferred file format in the pop-up box. Click the blue button next to the desired format. Read more about the different file formats in the next section of this article.
You can now download your files from the "Files" modal.
CSV format
You have the following options for exporting CSV files:
"1 hour", "15 min" and "Detailed" contain data for all activitiy categories. Select the degree of detail that best suits your data processing needs.
"Accelerometer Data" contains a BIN-file with raw accelerometer data.
|
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. |
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. Below is an example of an excerpt from a PDF report.
(Excerpt from a PDF report)
| Note: It is possible to create a PDF report for a maximum of 14 days due to the large amount of data. |
You have the following options for PDF reports:
The "Summary Report" includes a summary of the monitor period with average activity per day, a pie chart and a bar chart.
"Details for all days" includes a detailed view of each day in the monitor period like what you see in the web app.
"Combined Report" is a combination of the "Summary Report" and "Details for all days".
Accelerometer data in BIN/HEX or CSV format
Below is a guide on how to export raw accelerometer data. If you wish to export in BIN format we suggest following the guide in the section Export data in CSV or PDF format.
1) Enter the "Sensors" tab from the top menu bar. Select the sensor you wish to export data from.
2) Select "Accelerometer" in the export menu.
The graph show data in hourly intervals. To zoom in, simply click on an hourly interval. This displays the data in minute intervals for the selected hour.
3) Click "Export"
4) Select CSV or Raw.
5) Define the export period.

Note: Beware that it is only possible to export data for 14 days due to the large amount of data. |
6) If you have chosen to export raw data, choose "Hex" for HEX format or "Binary" for BIN format.
Hex format uses ASCII Hex with "new line" every 12 bytes. The format can be loaded in a text editor. Binary format is more 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

7) You can now download your files from the "Files" modal.
Downloading data
1) After initiating file generation as per the guides in this article, the files will be available in the "Files" modal which can be accessed in the top menu bar.
You can follow the progress of the file generation in the status bar. You may open and close the "Files" modal as you wish. This allows you to generate several files simultaneously in order to quickly download the files you need.
2) When your files are ready for download, a blue dot will appear next to the "Files" button:
Click "Download file" to download the file to your device.
