IoT Based Air Monitoring System

The level of pollution has increased with time by lot of factors like the increase in population, increased vehicle usage, industrialization and urbanization which results in harmful effects on human wellbeing by directly affecting health of population exposed to it. In order to monitor in this project, we are going to make an IOT Based Air Pollution Monitoring System in which we will monitor the Air Quality over a web server using internet of things over a cloud server means when there is sufficient amount of harmful gases present in the air like CO2, CO, smoke, alcohol, dust and NH3. It will show the air quality in PPM on the LCD and as well as on cloud server (things speak) so that we can monitor it very easily. We have used MQ135, MQ7 and Dust sensor which are the best for monitoring Air Quality as it can detect most harmful gases and can measure their amount accurately. In this IOT project, you can monitor the pollution level from anywhere using your computer or mobile. We can install this system anywhere and can also trigger some device when pollution goes beyond some level, like we can switch on the Exhaust fan or can send alert SMS/mail to the user.
