1. A vaporizer device comprising:
a heater configured to vaporize a vaporizable material; and
one or more controllers configured to perform operations comprising:
determining an amount of power applied to the heater,
determining a first temperature of the heater at a first time, the first time being at or after a start of a first dose interval,
determining a second temperature of the heater at a second time, the second time subsequent to the first time, and
calculating, based on the amount of power applied to the heater, the first temperature, and the second temperature, an estimated amount of the vaporizable material delivered to a user during the first dose interval corresponding to a first puff,
determining whether the estimated amount of the vaporizable material meets or exceeds a first preset threshold, wherein the first preset threshold corresponding to a preset vapor amount threshold per puff,
adjusting the first preset threshold for a second dose interval corresponding to a second puff based on the estimated amount of the vaporizable material, and
calibrating the vaporizer device based on the estimated amount and the adjusted first preset threshold.
