Messwerk shows and plots values from the different sensors of your phone.

It currently supports:

  • Accelerometer
  • Gyroscope
  • Rotation
  • Magnetometer
  • Light sensor
  • Proximity sensor
  • Position and signal strength of GNSS satellites
  • User coordinates in various formats and GNSS precision info

The data from all sensors can be logged to CSV files. Please note that this can drain your phone’s battery, as the system is prevented from entering deep sleep while logging is active.

The source code is available on Github. If you notice any bugs, please report them in the Github issue tracker.

Hi,
Would it be possible to add mic(s) to sensor list?
Also possibility to select only one sensor e.g. acc(x) and show it and FFT of it.

Great app. In satelite view, Glonass or GPS tracking or both ?

It should show both, as sometimes there are more satellites visible than GPS has in total (about 30). My guess is that the ones with IDs below 40 are GPS and the ones above are Glonass.

In the QtPositioning API, a property for the satellite system is provided, but it looks like this is currently unused at least on the Jolla phone (zeros are returned for all satellites, regardless of their IDs). So I can't really display this information at the moment.

Great app indeed, but data logging is a must before it's of any use. Also an option to prevent the screen from turning off would be nice.

Great app. It would be even better if you could save sensor data to text file.

Thanks for the comment. Data logging is actually the one feature that I miss myself :-) . So I will probably implement it for the first update.
