A wireless sensor system was used to monitor carbon monoxide and smoke air pollutants. A MATLB curve fitting toolbox was used to read both CO and smoke readings with a single sensor (MQ2). The system have an HTML-based interface developed in MATLAB software for displaying the pollutants level in parts per million gathered by the commercially available sensor. The paper presents a system which provides a low cost data acquisition of CO and smoke pollutants that can be read online for air pollution monitoring for environmental awareness. In addition, the MQ2 sensor can read other pollutants which could be added to the system for future work.
