Abstract:
Detection of low concentration of air pollution, like cigarette smoke, cooking fumes, etc. is possible with the combination of an air quality sensor and data acquisition system. In present paper is presented approach for design and implementation of air quality monitoring system based on tin dioxide gas sensor, integrated temperature and humidity sensors, portable modular data acquisition system and graphical programming language. An interpolation method reducing influence from temperature and humidity is suggested. This approach can be used for automatic controls in ventilation systems by detecting rapid changes in the air quality from the base levels.
