Abstract
Vaporization devices, components, and methods of operating them are provided. In some implementations, an apparatus includes a microcontroller, a battery, and electrical circuitry comprising a reference resistor, a first switch, a second switch, and a voltage divider. The microcontroller is configured to operate the first switch to interrupt a flow of current supplied from the power source through a resistive heating element, and to operate the second switch to add the reference resistor in series with the resistive heating element. The microcontroller is further configured to determine a resistance of the resistive heating element based on a voltage measured by the voltage divider when the reference resistor is in series with the resistive heating element, and to control an amount of power supplied to the resistive heating element based on the determined resistance by adjusting the flow of current supplied to the resistive heating element.
