+The sportssensor acts like a little USB storage device. Just plug it in to your computer. It will present it self as a drive called "SPORTSSENS". '''It is highly recommended to copy the data files from the sportssensor to you computer before further processing in Excel or Matlab'''. This can be done using e.g. Windows explorer (stifinder), MacOS finder or similar.
 === Stream live data ===
 When connected to your computer, the sportssensor presents a USB serial connection where live data can be streamed from. Use Windows device manager (enhedshåndtering) to determine which COM port the sportssensor is on. You can use the [https://www.arduino.cc/en/software Arduino IDE] serial monitor or [https://www.putty.org PuTTY] serial feature to view live data from the sensor.
