Patent attributes
An electronic vapor provision system including: a vaporizer for vaporizing aerosol precursor material for inhalation by a user of the electronic vapor provision system; a power supply for supplying power to the vaporizer; a wall defining an air flow path along which air travels through the electronic vapor provision system when a user inhales or exhales on the electronic vapor provision system; a temperature sensor mounted in the air flow path adjacent a portion of the wall of the air flow path; and a controller configured to cause power to be supplied to the temperature sensor to heat the temperature sensor and to cause power to be supplied to the vaporizer to vaporize the aerosol precursor material in response to detecting a change in temperature of the temperature sensor; wherein the air flow path is arranged such that, during inhalation or exhalation by the user, air travelling along the air flow path is directed at the temperature sensor in a direction that is towards the portion of the wall adjacent to which the temperature sensor is mounted so as to disrupt the airflow around the temperature sensor.
