Wireless sensor network based pollution monitoring system in metropolitan cities

Pollution detection and monitoring is very crucial task in todays world. To create better and safer environment for human being, animals, plants we need to monitor and control the pollution. This study proposes air pollution and monitoring model which detects pollution in air on the basis of data mining algorithm. The sensor grid is used to detect the sensor values from different gas sensors. Microcontroller is used to transfer the values from ADC to server. Data mining is used to calculate the pollutants from different areas. ID3 algorithm is used to calculate the values base on probability. Bluetooth module is used to connect the controller with client and the client connects with the server via web services. Wireless sensors are used to calculate the percentage of harmful gases present in the air that ultimately helps to provide the reduction in pollution. This system not only calculates the pollutants present in the air but also we can forecast to avoid future pollution in and can send the warning message to the particular polluted area. Here we consider mainly the chemical Industry near Pune and the I.T. area like Hinjewadi.
