I've tested the example code and varied the measurement read interval from 0.1 to 10 seconds. The readings exhibit similar noise (standard deviation) regardless of the read interval. This seems to indicate that the sensor is still just sampling the pressure value. Same is true if the averaging boolean is set true or false with a 10 second interval between reads.</p>

would it be possible to use it for a Pitot tub ?</p>

You can find the datasheets in the hardware repo:<p>https://github.com/sparkfunX/Qwiic_Differential_Pressure_Sensor-SDP31/tree/master/Documents</p><p>Best wishes,

Application of interest: with an open ended hose measuring the depth in a shallow pool or stream. Though the full range is only 2 inH2O. :^(
Nice resolution and +-3% accuracy!
I know i'm being lazy (again/still), but you usually have a link to the datasheet,..?</p>
