Airflow is what you want to know; after all, fans are there to cause airflow.
The problem with barometric pressure sensors, is that they’d measure static pressure, which from a single sensor, is not informative (changes with the weather, depends on altitude, etc.).
A case could use the difference between 2 sensors: outside/intake, vs. inside. If there was a pressure differential buildup, it would indicate a blocked output, while no difference in pressure, would indicate a blocked intake.
That’s still 2 sensors instead of 1, with some processing and possibly calibration going on… but could be interesting.
