Air pressure data is mainly used for CO2 altitude compensation, but it can also be used to ensure that vac sealed bags are under pressure. Using two devices, you can also use it to understand a room's pressure differential (whether airflow is negative or positive).

Take a look at the data shown below. The blue data is from a device outside of the tent, the orange data is from a device inside of the tent, and the green lines show when the exhaust was activated. The grey data is the difference in air pressure between the devices. As seen on the graph, the device on the inside of the tent (orange) shows that the air pressure reduces upon exhaust activation, as there is now negative pressure inside of the tent.
