Abstract
The nicotine electronic vaping device includes a nicotine reservoir, a heater and processing circuitry. The processing circuitry is configured to: determine a plurality of resistance values for the heater during a time window; calculate a percent change in resistance of the heater between a first of the plurality of resistance values and a second of the plurality of resistance values; decide whether the percent change in resistance of the heater exceeds a percent change in resistance threshold; and disable power to the heater in response to deciding that the percent change in resistance of the heater exceeds the percent change in resistance threshold.
