Data Acquisition

In data acquisition mode the SensBox will record the data of all internal sensors in high resolution at high speed for up to 24 hours. Recording rate is 20 Hz for the magnetic, acceleration and gyro sensors in all directions with the corresponding pitch, yaw and roll values. Pressure-based values such as height and vario are logged at 8 Hz. GPS data is recorded at 5 Hz. The output is saved as CSV file and can be further processed in Excel, Matlab, etc.

Instrument Configuration

SensBox Configuration Tool v0.12
The SensBox configuration is stored in the file FScxxxx.cfg file in the System folder on the SensBox SD card (xxxx is the SensBox serial number including leading zeros). If the configuration file is missing (e.g., new SD card), please create a empty file named FScforce.cfg and save this file on the SD card in the System folder. Insert the SD card into the SensBox, turn the device on, then off and the SensBox will automatically save the SensBox's current configuration to a file named FScxxxx.cfg

Use the Configuration tool below to set SensBox thresholds, parameters, settings and user-data and save as a configuration file. In the Configuration tool, File>Save will save settings to file named FScforce.cfg. Replace the FScxxxx.cfg file in the System folder on the SensBox SD card with the FScforce.cfg (this can be done directly to the SD card or via the USB connection).

Firmware

Copy the new firmware file to the Sensbox via the USB connection or directly onto the SD card, into the “system” folder. Only one firmware file (*.upg) is allowed in the system folder, otherwise an error message will appear during installation, and the installation process will be aborted. To install the new firmware, hold down the OK/Func button while turning the Sensbox on. The display will show UPG (upgrade) with a moving segment to indicate that the installation is in progress. After the installation, the Sensbox turns itself off automatically.

SensBox v3.02
This version combines flight and logger functionality into one firmware. With this version, press power key to start-up SensBox, chose between "FLY" (flight mode) and "LOG" (data logger mode) with ↑ or ↓ keys and confirm by pressing OK key. In flight mode the flight is recorded as an IGC file in the Tracks directory on the SD card. In logger mode, logging is started with a press of the Start key and stoped with a press of the Stop key (confirmed with a press of the OK key). This creates a CSV file in the Logs directory.
