Integrated chemical sensor for detecting odorous matters

A method, comprising:

• detecting odorous substances through a cartridge-like chemical sensor, the detecting including:
• feeding a gas to be analyzed to an input opening of a housing of the chemical sensor;
• generating a stream of the gas to be analyzed along a channel and on an integrated device having a sensitive region of a material configured to bind with target chemicals in the gas to be analyzed;
• driving the gas to be analyzed toward an output hole.

A chemical sensor, comprising:

• a housing that includes an input opening, an output hole, and a channel for a gas to be analyzed, the channel extending between the input opening and the output hole, the channel having a test portion laterally defined on opposite lateral sides by internal protruding structures extending interiorly from an inner surface of the housing that defines a first one of upper and lower sides of the channel;
• a circuit board positioned interiorly of the housing and in contact with the protruding structures, the circuit board having a surface defining a second one of the upper and lower sides of the test portion of the channel;
• a integrated device fixed to the board and including a sensitive region open in the test portion of the channel and of a material configured to bind with target chemicals in the gas to be analyzed;
• and
• a driving motor for advancing the gas to be analyzed, the driving motor being housed in the housing and positioned between the integrated device and the output opening.
