Abstract
A vaporizer device may include a pressure sensor and an ambient pressure sensor. The pressure sensor may be configured to measure a first pressure in an air flow path in the vaporizer device. The ambient pressure sensor may be configured to measure a second pressure corresponding to an atmospheric pressure. The vaporizer device may further include a controller. The controller may be configured to transition the vaporizer device to a first standby mode when the first pressure is equal to or greater than the second pressure for a first threshold quantity of time. While the vaporizer device is in the first standby mode, the controller may be further configured to transition the vaporizer device to a second standby mode when the second pressure is a threshold quantity greater than the first pressure and no motion event is detected for a second threshold quantity of time.
