Air pollution is contamination of air with poisonous substance where the air is unfit to breathe and not only affect
humans but also all living things in the environment 90% of the people in the world breathe polluted air at present air pollution
is the thread to human life the entire pollution is affected by it. Some gases which causes air pollution are nitrogen oxide,carbon
monoxide, carbon dioxide and sulphur oxide. The combusion of fossils at power plant and industries are responsible for air
pollution. Sulphur dioxide which leads to heart disease and gases like carbon dioxide which leads to stopping of oxygen also
leads to death thus to make human aware of air the air they breathe and to know about their environmental situation the
proposed solution is used where an arduino which is attached to a gas sensor the gas sensor collects all the gases and transmits
to arduino this stores all the value in cloud as soon as the value reaches high the user will receive an alert in webpage about the
level.
