Emergence of environmental issues such as air pollution has greatly required the need for robust, cheap, operationally adaptable, and smart monitoring systems. The proposed work describes a study of how the household plants are helpful in purifying the environment. Air pollution monitoring system has been developed using Wireless Sensor Network (WSN). Sensor nodes and embedded system are used for monitoring air quality. The monitoring system consists of sensor nodes, base station and PC for data processing, storage, and presentation. Once data is collected at PC, it is then compiled and presented on web server.
