Abstract

An aerosol-generating system has an optical sensor disposed on a portion of an exterior surface of the aerosol-generating system. The optical sensor is configured to output sensor data. A controller is operably coupled to the optical sensor. The controller is configured to manipulate one or more operating parameters of an aerosolizer element of the aerosol-generating system based on the optical sensor data.

Claims (21)

1 . An aerosol-generating system configured to use an aerosol-generating article to generate aerosol for inhalation by a user, the system comprising:

an optical sensor configured to sense and output sensor data that corresponds to a color detected by the optical sensor when the user places the aerosol-generating article in optical communication with the optical sensor; and

a controller operably coupled to the optical sensor, the controller is configured to change a temperature profile of the aerosol-generating system based on the sensor data output by the optical sensor.

2 . The aerosol-generating system according to claim 1 , wherein the aerosol-generating article comprises an aerosol-generating substrate.

3 . The aerosol-generating system according to claim 2 , further comprising an inductive coil configured to transfer electromagnetic energy to a susceptor.

4 . The aerosol-generating system according to claim 3 , wherein the susceptor is configured to heat the aerosol-generating substrate to form the aerosol.

5 . The aerosol-generating system according to claim 2 , wherein the aerosol-generating substrate is solid at room temperature.

6 . The aerosol-generating system according to claim 2 , wherein the aerosol-generating substrate comprises tobacco or a tobacco-containing material.

7 . The aerosol-generating system according to claim 1 , wherein the optical sensor comprises a chromatic sensor.

8 . The aerosol-generating system according to claim 1 , wherein the optical sensor comprises a light source and the optical sensor is configured to sense light from the light source that is reflected off a colored surface proximate to the optical sensor.

9 . The aerosol-generating system according to claim 1 , wherein the controller comprises memory storing a plurality of aerosol forming heating profiles, wherein each heating profile is associated with a color detected by the optical sensor.

10 . The aerosol-generating system according to claim 1 , further comprising an aerosol-generating device configured to receive the aerosol-generating article.

11 . The aerosol-generating system according to claim 10 wherein the aerosol-generating device comprises the controller and memory.

12 . The aerosol-generating system according to claim 10 , wherein the aerosol-generating device comprises an aerosolizer comprising an atomizer, cartomizer, heater or an inductive coil.

13 . The aerosol-generating system according to claim 12 , wherein the controller is configured to activate the aerosolizer to generate aerosol from the aerosol-generating article according to an aerosol delivery profile stored in memory.

14 . The aerosol-generating system according to claim 1 , further comprising a display configured to display graphics based on the color.

15 . The aerosol-generating system according to claim 1 , further comprising packaging for containing aerosol-generating articles.

16 . The aerosol-generating system according to claim 8 , wherein the optical sensor comprises a solid state light source.

17 . The aerosol-generating system according to claim 10 , wherein the aerosol-generating device comprises a display configured to display graphics based on the color.

18 . The aerosol-generating system according to claim 1 , wherein the controller is configured to modify an aerosol delivery profile based on the sensor output data.

19 . The aerosol-generating system according to claim 18 , wherein the aerosol delivery profile describes how aerosol is generated from an aerosol-forming substrate and delivered to a user.
