摘要： An aerosol delivery device is provided that includes a reservoir configured to retain aerosol precursor composition, a valve configured to control a flow of aerosol precursor composition from the reservoir to a heating element controllable to activate and vaporize components of the aerosol precursor composition, a sensor configured to measure reflectance or temperature at the heating element and generate a signal corresponding to the reflectance or temperature so measured, and a control component. The control component controls operation of the valve including receiving the signal and based thereon determining a volume of aerosol precursor composition at the heating element, and causing the valve to decrease or increase a rate of the flow of aerosol precursor composition in response to the volume being respectively above or below a predetermined threshold volume.
