Towards a Real-Time Air Pollution Monitoring Systems Implemented using Wireless Sensor Networks: Preliminary Results

This paper describes the preliminary results obtained towards the development of a Wireless sensor network for monitoring air quality parameters within smart city applications. The system is implemented based on distributed sensor nodes using wireless technology. Several low cost sensors were placed inside a PVC chamber in order to monitor air pollutants concentrations. To test the system, data samples were obtained around to two cities to determine the CO2 concentration and particulate material levels. Preliminary results suggest that wireless system developed may be used as a low cost tool for air pollution monitoring.
