No, not really. There is sensing tube (which terminates on the sensor) and a venting tube (which lets the air flow through). This is the same technique used in other similar commercial instruments. You can see both tubes in the assembly instructions: https://github.com/jcard0na/haxo-hw/blob/main/docs/assembly....

Ahh that makes sense! So is this actually sensing a lower pressure than ambient? Since moving air results in lower pressure?
