Hi terrain_inconnu, a good example of using an Arduino Nano 33 BLE Sense to communicate with Phyphox.
It's also an excellent example of the use of Phyphox's graphics capabilities that I plan to take note of for my future work.
The accuracy in measuring the speed of sound is very good and I would like to propose to you to use this same arrangement to measure the speed of sound but for gases other than air.
If you place the ultrasonic emitter at the end of a tube of known length and opposite this face of the tube, place a flat surface, and put an inlet and outlet on this tube to fill it with some gas other than air, you could measure the speed of sound for this gas. To explain myself better, I leave you with a reference to a device that I designed, also using an ultrasound sensor to make precisely this type of measurements in gases other than air.

At that time I didn't use Phyphox because my Arduino wasn't BLE (Arduino Nano V 3.0 CH340) but I think that based on the files you shared I might think about buying an Arduino Nano 33 BLE Sense
Best regards
Alberto
