An aerosol generating device includes a heater that heats an aerosol generating substrate, a temperature sensor that detects a temperature of the heater, and a controller that controls power supplied to the heater through a power signal such that the heater is heated within a preset temperature range, filters the power signal, and detects a user's puff based on the filtered power signal. Accordingly, the aerosol generating device according to the present disclosure may more accurately detect a user's puff.

Methods and vaporizer apparatuses that estimate, measure and/or predict the amount of vapor and/or material (including active ingredients) released by the vaporizer apparatus. In particular, described herein are electronic vaporizers and methods of using them that determine a dose/amount of vapor and/or a material in the vapor based primarily or exclusively on the electrical and thermal properties, e.g., power or energy applied to the vaporizing element (e.g., heating coil) and the temperature of the material immediately before and as it is vaporized. Dose information may be used to control operation of the device and/or reported to the user.

A vaporizer device may include a vaporizer body configured to couple with at least one vaporizer cartridge including a first reservoir and a second reservoir. The vaporizer device may include a first aerosol generation mechanism configured to generate a first part of an aerosol by at least vaporizing a first aerosol component present in a first vaporizable material in the first reservoir. The vaporizer device may also include a second aerosol generation mechanism configured to generate a second part of the aerosol by vaporizing a first aerosol component present in a second vaporizable material at a second temperature. The first part of the aerosol and the second part of the aerosol may be delivered, via a mouthpiece, to a user of the vaporizer device.
