Airflow sensors

The amount of air entering your engine is a  mesaurable value.
This  undertaken either by a moving vane air sensor or more commonly a MAF or mass airflow unit.
The early MAFs were literally a  heated wire,the amount of air  was detected by the level of current needed to maintain the wires temperature.
All a bit hit and miss and prone to a lot of failures. Todays MAFs use thin film technology giving far quicker responses to changing air flow conditions
