Because of their low cost, compact size, and fast response, electronic noses are widely employed in a
variety of industries, including medical care, food. The Electronic Nose (E-Nose) is a device that
simulates the human olfactory system. It assesses gases and scents qualitatively and quantitatively. It is
also referred to as a simulated olfactory system. It is made up of a sensor array, appropriate pre-processing
analysis, and a pattern recognition system for efficient classification. This research project proposes a

Common respiratory tract infections can cause severe morbidity and mortality when they impact the lungs
and lower airways. Survival rates would be significantly higher if the disease was diagnosed and treated
clinically earlier. Many studies have shown that certain diseases and infections can result in characteristic
changes in VOC profiles in the exhaled breath. For the diagnosis of these conditions, a system and
apparatus that are simple to use, non-invasive, yield highly accurate results, and have the fewest possible
