hor63's point of view is a bit extreme. One thing Johanan forgot to mention was the required accuracy of the system. If indeed the sensor system needs to detect a 10-50Pa signal, then yes this is feasible. If the sensor system needs to accurately measure it, not so much. In a previous test comparing 2 BMP388 sensors output at rest over 2 days, I observed a typical deviation (68%) within +-3.2 Pa, and a maximum deviation (99.7%) within +-9Pa. Therefore, I would go on to say that using 2 BMP388 absolute pressure sensor, you can detect a signal greater than 10 Pa with few false negatives. o_o
