Sensor networks have presently been an active research area mainly because of the significance of their applications. This project proposes to implement wireless sensor networks based Air pollution monitoring. RSPM (Respirable Suspended Participate Matter), Carbon Dioxide (CO2) and Nitrogen Dioxide (NO2) from the air are monitored as these gases determine the level of pollution. The use of MQ-6, MQ-135 sensors enabled us to monitor the Carbon Dioxide and Nitrogen Dioxide levels in the atmosphere. Also temperature and humidity is monitored using DHT11 sensor. The Atmega processor is used as the prominent platform for interfacing those sensors and the sensed data is processed wirelessly through Zigbee modules (Xbee S2C). The data hence received from the sensor device is simultaneously stored in a system as a help for a future reference in the levels of contamination. Thus with the help of the collected data, proper precautions can be taken to minimize the pollution levels in the air thus making human life sustainable.
