Fatigue Sensors

The fatigue sensor accessories are capable of capturing photos when a fatigue related event is caught.

The images that are saved automatically to the default directory can be uploaded via ftp using lftp

Check out our LFTP tutorial on the Bash/Shell scripting page for information on how to upload and sync photos with a remote server.

Tips

Take note of the amount of space occupied by the photos in the /data/users/syrus4g/fatigue_sensor folder.

Once your application has received a photo you may want to delete them based on the epoch

$ rm 16158136*

If you lower the buffer size it will delete the oldest photos over the new size limit.
