Abstract

Quality of indoor air (IAQ) is one of considerable concerns of today. Its evaluation through measurement is highly requested, but difficult. The reason is the numerosity of influencing factors involved as well as sig- nificant temporal and spatial variability of IAQ. In this work, we proposed a sensor system with multi-point sampling for this purpose. It is based on semiconductor gas sensor. The measurements were performed in a concert hall. The measurement procedure included sensor exposure to gas samples delivered from four sampling points, interchangeably with purified air for sensor regeneration. The obtained results show that the sensor system with multi-point sampling is a promising concept for indoor air monitoring. It was demon-strated that the system is applicable to determine the influence of occupants on IAQ. It is possible, because human beings release VOCs, which are measurable by semiconductor gas sensors. Sensor regeneration plays crucial role in the system operation. For achieving valuable results it is necessary to apply sensor signal pre-processing, which consist in baseline correction.
