description: The work is devoted on the topic âMonitoring the concentration of oxygen in the exhaust gases of boiler unitsâ and aims to increase the efficiency of the use of natural fuel in the generation of thermal energy in boiler plants. This goal was solved by implementing a continuous process for monitoring the concentration of oxygen in the exhaust gases of boiler units based on the development of appropriate hardware and software. The choice of the optimal oxygen sensor for the control system was made from almost all of their diversity on the market. A measurement and display board has been developed that allows real-time measurement, control and visual display of the current value of the gas mixture concentration. Structural and circuit diagrams of its construction are proposed, and the corresponding algorithm and software implementation of its functioning are developed. The practical part of the work was carried out on the basis of the Uran-SPb NPF and was carried out on the basis of the developed test program, during which the optimal Bosch LSU 4.9 broadband sensor was selected. Measurement errors and the influence of various factors on the measurement process were evaluated. The results of the work can be used in the development of industrial samples of equipment for monitoring the concentration of oxygen in the exhaust gases of boiler units.
