The paper presents Wireless sensor network system used to monitor and control the air quality in Nagpur city. Environmental air pollution monitoring system that measures, RSPM (Respirable Suspended Particulate Matter), NOx, and SO2 are proposed. The traditional air quality monitoring system, controlled by the Pollution Control Department, is extremely expensive. Analytical measuring equipment is costly, time and power consuming, and can seldom be used for air quality reporting in real time. Wireless Sensor Networks are a new and very challenging research field for embedded system design automation, as their design must enforce stringent constraints in terms of power and cost. Wireless Sensor Network is a fast evolving technology having a number of potential applications in various domains of dailylife, such as structural and environmental monitoring, medicine, military surveillance, condition based maintenance etc. A WSN is composed of a large number of sensor nodes that are usually deployed either inside a region of interest or very close to it. WSN nodes are lowpower embedded devices consisting of processing and storage components (a processor connected to a RAM and/or flash memory) combined with wireless RF transceiver and some sensors/actuators. Designing a WSN node is a complex task, since the designers must deal with many stringent design constraints.
