摘要：we are making an IOT Based Air Pollution Monitoring System to monitor the real time air quality of the specific area. In this project we will monitor the Air Quality over a web server using internet. We are also going to trigger an alarm when the air quality goes down beyond a certain level so that we can warn the people of the respective area. Air Quality going below the optimal value is representing that there are exceed amount of harmful gases, present in the air like CO2, smoke, alcohol, benzene and NH3. It will show the Air Quality in PPM (Parts per Million) on the LCD display and as well as on webpage so that we can monitor it very easily. Earlier we have built the LPG detector using MQ6 sensor and also Smoke detector using MQ2 sensor. In this project we are using MQ135 sensor which is the best choice for monitoring Air Quality as it can detects mostly all harmful gases and also can measure their amount accurately at an extent. In this IOT project, we can monitor the pollution Level from anywhere using our Computer, Laptop or Mobile. We can install this system anywhere and can also trigger some device when we observe the air quality is much polluted that can harm the people in that particular environment.
