Thermodynamic Equations of Nonequilibrium System for Measuring Odors by Gas Analyzers. Practical Example of a Microcontroller Calculation for Digital Odor Detection by Gas Analyzers

Abstract— A method for the digital measurement of odors using gas analyzers is presented. This capability enables a new level of precision in identifying spoiled products (e.g., in grain storage and transportation), detecting narcotics, digitizing odors in the culinary and cosmetics industries, and developing olfactory television. This paper details a measurement approach and methodology based on thermodynamic equations for a nonequilibrium odor measurement system. A practical example of a microcontroller calculation for a digital odor detection device using MQ-type gas analyzers is provided, including the process for determining the empirical coefficients integrated into the algorithm.
