It is shown that optical gas sensors have additional possibilities of ensuring their selectivity in comparison with electrical sensors due to comparison of changes in optical properties under the influence of gases at different wavelengths. It is shown that the presence and position of the isosbestic point in the absorption spectra of polymer films depends on their chemical composition and can be effectively controlled to ensure the selectivity of optical gas sensors based on them. The patterns of changes in optical absorption in combined thin-film polymer active elements for gas sensors based on a mixture of polyorthotoluidine and polyorthoanisidine have been established, which allow selectively identify the presence of ammonia, hydrogen sulfide, and carbon dioxide. The principles and processes of adaptation of the microprocessor signal converter for integrated sensor devices, which is based on the concepts of embedded systems and System-on-Chip system for the gas sensor proposed by us, are proposed. A method of selective analyte detection by an optical gas sensor based on optoelectronic pairs with a mobile matrix of LEDs and photodiodes and the possibility of simultaneous registration of independent signals of parallel optocouplers.
