Air pollution has a very adverse impact on human beings and our ecosystem. With the rampant industrialization and exponential growth in automobile industry, the air gets highly contaminated by harmful toxins & gases released from their emissions which results into many hazardous diseases like asthma, bronchitis, mental illness, lung cancer etc. Hence the air pollution should be carefully monitored and efficiently controlled. Using internet of things (IoT) we can simultaneously gather pollutants level in highly explicit areas and transmit the data to centralized controlling and monitoring unit where suitable steps can be taken to warn people so as to reduce the level of pollutants in the air significantly.
