Hello,
I have tried the program mentioned above and also observed some kind of regular peaks (Pressure pulses 2021-08-30 20-50-27.png) that I have never seen before. I have only modified the phyphox code (pressure_plot_v1a.phyphox) for the pressure acquisition in order to see better the peak heights.
So, I have verified pressure recording using my own programs (bar_arduino_nano_fast.zip; bar_arduino_nano2.phyphox) and have not seen such peaks (Pressure from Arduino 2021-08-30 21-00-35.png).
Pressure variations observed are real as can be seen using two different pressure sensors
Here is the code for two sensors (bar_Arduino_SensorTag.phyphox) and the corresponding result (Pressure from Arduino and SensorTag 2021-08-30 21-03-11.png).
