Real-Time Indoor Air Quality Monitoring Through Wireless Sensor Network

Recently, indoor air quality monitoring (AQM) has become an important research area for the concern of human health and lifestyle. The AQM is usually based on the deployment of wireless sensor networks (WSN) within the building. Bridging the gap between gas sensors, deployed at different locations of the WSN, and the Internet becomes a challenging task in terms of link reliability and data integrity. Recent advances in the design of Internet-of-Things (IoT)-enabling solutions are spurring the advent of novel and fascinating bridging. In the wake of this tendency, this paper proposes a novel, IoT Smart architecture for air quality monitoring. With the IoT vision, we propose a Smart global AQM system, which employs different, yet complementary, technologies, such as gas sensing, WSN and Smart mobile. Our proposed system, is able to collect, in real time and from different cities, data related to the concentrations of critical gases, humidity, and temperatures. Collected data are delivered to a local gateway where an advanced processing makes them easy and accessible by both, local and remote users via a remote web server.
