Abstract: The increase in pollution everywhere, due to increase in urbanization and industrialization, attracts the major concern of all the authority and the people at global level look forward to find out the way to resolve it. Pollutants are the substances that cause pollution and that affect the environment. Though the efforts were to control air pollution have traditionally focused on the outdoor air, it is now apparent that high concentrations of contaminants are common inside most private and public buildings (indoor air). The concerns about public health problems increase here due to indoor air pollution and are based on the fact that states, urban residents usually spend more than 90 percent of their time indoors, and the concentrations of some contaminants are higher in indoors than outdoors, and some of the pollutants personal exposures are not characterized effectively by outdoor measurements. Our idea is based on the NASA Clean Air Study. This idea is mainly focusing on reducing indoor air pollution through the use of plants. Index Terms - Clean Air Study, Volatile Organic Compounds, Air Pollution, Hydrocarbons, Humidity. I. INTRODUCTION In this idea, the leaves, roots, soil, and associated microorganisms of plants have been evaluated as a possible means of reducing indoor air pollutants. Additionally, a novel approach of using plant systems for removing high concentrations of indoor air pollutants such as cigarette smoke, organic solvents, and possibly radon has been designed from this work. This air filter design combines plants with an activated carbon filter. The rationale for this design, which evolved from waste water treatment studies, is based on moving large volumes of contaminated air through an activated carbon bed where smoke, organic chemicals, pathogenic microorganisms (if present), and possibly radon are absorbed by the carbon filter. Plant roots and their associated microorganisms then destroy the pathogenic viruses, bacteria, and the organic chemicals, eventually converting all of these air pollutants into new plant tissue. It is believed that the decayed radon products would be taken up the plant roots and retained in the plant tissue. The system is based on the NASA Clean Air Study. The NASA Clean Air Study was a project led by the National Aeronautics and Space Administration (NASA) in association with the Associated Landscape Contractors of America (ALCA) to research ways to clean the air in space stations. Its results suggested that, in addition to absorbing carbon dioxide and releasing oxygen through photosynthesis, certain common indoor plants may also provide a natural way of removing volatile organic pollutants (benzene, formaldehyde, and trichloroethylene were tested). The study further suggested that efficient air cleaning is accomplished with at least one plant per 100 square feet (9.3 m2) of space, but was conducted under sealed space station conditions and research conducted since has shown mixed results in the home or office. II. INTERNET OF THINGS In the new era of communication and technology, the explosive growth of electronic devices, smart phones and tablets which can be communicated physically or wirelessly has become the fundamental tool of daily life. The next generation of connected world is Internet of Things (IoT) which connects devi ces, sensors, appliances, vehicles and other “things”. The things or objects may include the tag, mobile phones, sensors, actuators and much more. With the help of IoT, we connect anything, access from anywhere and anytime, efficiently access any service and information about any object. The aim of IoT is to extend
