Classification: CPC G  A | IPC A  G

Claim 12:
13. A system for identifying an insect infestation of a stored product, the system comprising:
a testing chamber enclosing a sensor array, wherein the sensor array includes a plurality of VOC sensors and at least one VOC sensor of the plurality of VOC sensors is configured to detect the presence of an insect egg-specific VOC;
an air transfer unit configured to retrieve a fluid flow and deliver the fluid flow to the testing chamber; and
a controller operatively connected to the air transfer unit and the sensor array, wherein the controller is configured to:
operate the air transfer unit to retrieve the fluid flow from and deliver the fluid flow to the testing chamber, wherein one or more of the plurality of VOC sensors are in fluid contact with the fluid flow;
operate the sensor array to measure a conductance for one or more of the plurality of VOC sensors;
determine a set of conductance change values corresponding to each of the one or more VOC sensors; and
determine a gas component concentration for one or more target VOCs within the fluid flow based on the set of conductance change values.
