Abstract: Air pollution is one of the environmental problems that must be solved. Heavy transportation and industrial activities may cause poor air quality and inhaling pollutants, such as CO and CO2, for a long time may damage human health. Therefore, it is necessary to have an air quality monitoring system which gives information of hazardous gases concentration from time to time in certain area. This study aims to design and build a monitoring and measurement system for CO and CO2 in the environment using wireless sensor network (WSN) with ZigBee based wireless network technology. The experimental results show the proposed system is able to provide the air quality monitoring in real time through WSN technology. In order to have accuracy measurement results, those sensors used in the developed system are compared and calibrated to reliable standard instruments. DHT 22 sensor works well as a sensor to read the temperature and humidity with an average error value of 0.14 ℃ and 0.1 % RH, respectively. The MQ-7 gas sensor has an average error of 72, 082 ppm and the MG811 gas sensor has an average error value of 281.36 ppm, both are compared to E4500-C standard instrument device.
