Abstract: Electrical cigarettes and methods for performing the operations thereof are provided. An exemplary method includes: receiving, from a pressure sensor, pressure sensor data; computing , using the pressure sensor data and average pressure sensor data, differential pressure data; determining whether the differential pressure sensor data meet a first criteria involving a first set of thresholds; upon determining the differential pressure data does meet the first criteria, determining whether the differential pressure sensor data meet a second criteria involving a second set of thresholds; upon determining the pressure data does meet the second criteria, issuing a trigger signal indicating enough differential pressure is present for smoking.
