1. A sensor device comprising:
a measuring transducer including a pixel array on which volatile compounds and water vapor are condensed and a sensitive porous dielectric layer provided in a form of a plurality of spheres constituting the pixel array;
a temperature controller provided around the pixel array, and configured to control temperature of each of pixels constituting the pixel array and temperature of the pixel array;
a detection device connected to the measuring transducer, and configured to detect a response pattern of the volatile compounds through the pixel array;
an analyzer configured to:
process the response pattern of the volatile compounds,
classify the response pattern according to predefined classes by using a predefined machine learning algorithm, and
store the response pattern and a classification result corresponding to the response pattern;
a stimulating source connected to the measuring transducer, and configured to stimulate the measuring transducer; and
at least one processor connected to the stimulating source, the temperature controller, and the analyzer, and configured to control parameters of the stimulating source and control the temperature of the pixel array by using the temperature controller,
wherein the pixel array is configured with a plurality of pixels each including two sub-pixels,
wherein the two sub-pixels are provided as a sub-pixel provided as a plurality of hydrophobic spheres and a sub-pixel provided as a plurality of hydrophilic spheres,
wherein each of the plurality of hydrophobic spheres shows higher reactivity to the volatile compounds than water vapor by using a coating of a preset material for condensing or adsorbing the volatile compounds in pores of the sensitive porous dielectric layer, corresponding to the respective hydrophobic spheres, and
wherein each of the plurality of hydrophilic spheres shows higher reactivity to the water vapor than the volatile compounds.
