1. A hand-held vapour generating device for producing a vapour for inhalation by a user, the device comprising:
an oven arranged to receive a vapour generating substrate;
an inlet;
an outlet;
an airflow passageway for providing a fluid connection between the inlet and the outlet via the oven and through which generated vapour can flow to the outlet;
a device controller;
a humidity sensor for generating a measurement of a vapour produced by said substrate, wherein the device controller is arranged to control operation of the device based on measurement data from the humidity sensor; and
a gas sensor for measuring adverse/undesirable components in the produced vapour, such that when the device controller determines that a substrate is genuine, based on the measurement data from the humidity sensor, said gas sensor takes measurement of the generated vapour.
