Aerosol delivery device

An aerosol delivery device comprising:

• a mouthpiece end;
• a primary air channel extending from an air inlet for the aerosol delivery device to an opening in the mouthpiece end;
• an aerosol generation chamber in fluid communication with the mouthpiece end via a portion of the primary air channel, wherein the aerosol generation chamber comprises aerosol generation means for generating an aerosol from a source material for inhalation by a user through the mouthpiece end during use;
• and
• sensor means for detecting when a user inhales on the mouthpiece end, wherein the sensor means is in fluid communication with the mouthpiece end via a secondary air channel, and wherein the sensor means is located further from the mouthpiece end than the aerosol generation means, and the secondary air channel bypasses the aerosol generation chamber such that the secondary air channel is separate from the primary air channel up to a location in the primary air channel which is downstream of the aerosol generation chamber.
