Smart Environment Monitoring System

One of the most serious problems that humanity and other life forms on our planet facing today is environmental pollution. The contamination of physical and biological components of the earth/atmosphere system which adversely affects normal environmental processes is called environmental pollution. Naturally occurring substances or energies when present in excess of natural levels, are considered as contaminants and are called pollutants. When natural resources are used at a rate higher than nature’s capacity to restore itself leads to pollution of air, water, and land. A pollutant can be any chemical or geochemical substance (dust, sediment), biological organism or product, or physical substance (heat, radiation, sound wave) that is released intentionally or inadvertently by man into the environment with actual or potential adverse, harmful, unpleasant, or inconvenient effects. Such undesirable effects may be direct or indirect, being mediated via resource organisms or climate change. This paper proposes an IOT based environmental pollution monitoring system that uses temperature & humidity (DHT11), Carbon Monoxide (MQ3), PH & soil moisture sensors that sense corresponding environmental parameters and when any of their values exceed the harmless threshold, authorities and public are notified. A periodical analysis of the collected data is performed to identify the critical parameter in an area during a particular time period. A web portal is also provided through which registered users can communicate rescue information among registered members.
