Sensorkraken

Sensorkraken is an Android app to record raw sensor data for later processing.
Sensorkraken collects raw sensor related data and provides them as structured data for later analysis on another machine. All available system sensors and some custom defined sources are used to record and export data for further analysis.

The interval and sensors to be used can be individually defined and thus enables a highly customizable data collection application. Sensorkraken only aims at collecting data and not analyzing/visualizing.
