AIR QUALITY MONITORING BASED ON METAL OXIDE GAS SENSORS AND ZIGBEE TECHNOLOGY

Air pollution is a major problem for the environmental health, affecting both developing and developed countries. Inhaling pollutants is very harmful for human health, hence, the air quality monitoring is an essential task. The development of the sensor technology and wireless communication has led to the rapid growth of wireless sensor networks (WSN), which present a great technology for detecting, measuring and gathering information from the real world (weather and traffic conditions, air quality etc.) and to transfer them to end users. Conventional methods of air quality are very expensive and are great consumers of electricity. The alternative to this method are the WSN systems which have small consumption and receive data on air pollutants in real time. This paper includes the overview of gas sensors and communication technology of WSN for air quality monitoring
