This study investigates the applicability of a sensor-based measurement system for monitoring gaseous pollutants (CO, NO<sub>x</sub>, SO₂) in small-scale industrial facilities. To ensure stable sensor operation, a preconditioning system was integrated and its effectiveness evaluated. The study focused on two distinct industries, chemical (plastic) and textile, to reflect diverse emission characteristics. The test-bed conditions were defined based on emission environments. The chemical industry exhibited an average temperature of 27°C and relative humidity of 60%, characterized by higher humidity. In contrast, the textile industry showed a higher temperature of 85°C and a lower relative humidity of 35%. The preconditioning system effectively stabilized sensor-operating conditions, achieving average temperatures of 18.9°C and 23.5°C and average relative humidities of 22.6% and 15.4% for the chemical and textile industries, respectively. This ensured compatibility with sensor operational requirements of -10°C to 40°C and 20~80% relative humidity. Absolute humidity removal efficiencies were 75.1% for chemical emissions and 97.6% for textile emissions, indicating higher efficiency in high-temperature, high- humidity environments. Emission monitoring revealed CO and NO<sub>x</sub> concentrations below 5 ppm for both industries, while SO₂ was undetected. Similar low-level concentrations of gaseous substances were observed with a co-located Tele-Monitoring System (TMS). These results were well below regulatory limits of 200 ppm (CO), 150 ppm (NOx), and 200 ppm (SO₂). Further research is needed to assess the performance of the sensor-based system in environments with higher emission gas concentrations, as the current study focuses on very low concentrations. This is to better understand its effectiveness in more diverse and challenging conditions, especially in scenarios approaching or exceeding regulatory limits.
