+--- Thread: Using Inclination and angular motion in "My experiment" option. (/showthread.php?tid=409)
Using Inclination and angular motion in "My experiment" option. - drhaiderali220 - 09-29-2019
Hello, can someone tell me how to use gyroscope and inclination ( both of these) in same " My experiment" option. In "Myexperiment" option , inclination is not in the list. Is there any way to do it. Thank you!

The "My experiment" function in the app is rather limited and only allows for simple combinations of raw sensor measurements. However, you can do much more with our experiment editor on https://phyphox.org/editor. There you can open the existing inclination experiment and simply add the gyroscope along with graphs to plot the data from the gyroscope (don't forget to add it under "export" as well to be able to save the data). When you have edited the experiment to your needs, you can simply generate a QR code to scan from phyphox to get your configuration into the app. The editor is a bit more complicated, but once you get the hang of it, you can do so much more...
Also, allow me to answer your other question from your direct message in the forum as well, as it might be of interest to other users as well.
Quote: And how can I reduce noise when I turn on gyroscope rotation motion in your app.
The easiest way is to reduce the sampling rate. For example, if you set the sampling rate to 10 Hz while your gyroscope can actually measure at 100 Hz, phyphox will still receive data at a rate of 100 Hz, but it will average 10 values to get down to 10 Hz. So, setting the rate in the "New Experiment" in the app or by setting it on the "input" tab of the editor, you will get reduced noise.
If you want something more sophisticated, you can implement it in the editor, although this quickly becomes more complicated. You could use an FFT and implement a low pass filter or you could use something like the "reduce" module to average a specific number of value and keep the original data at the same time.
I would suggest that you have a look at the info material about our editor (https://phyphox.org/wiki/index.php?title=Analysis_modules) (it's not entirely up to date anymore, but the principles are the same) and at the available analysis modules (https://phyphox.org/wiki/index.php?title=Analysis_modules). Then let me know if you have any trouble.
