Air contamination is the biggest ecological and general challenge to monitor and control on the planet today. The level of contamination is expanding quickly because of components like enterprises, urbanization, expanding in populace, vehicle utilize which can influence human wellbeing. Particulate issue is a standout amongst the most imperative parameter having the critical commitment to the expansion in air contamination. IOT Based Air Pollution Monitoring System is utilized to screen the Air Quality over a web server utilizing Internet. It will trigger a caution when the air quality goes down past a specific level, implies when there are adequate measure of destructive gases present noticeable all around like CO2, smoke, liquor, NH3 and NOx. It will display the air quality in parts per million on the LCD and also on website page with the goal that air contamination can be checked smoothly. This paper introduces a continuous air quality checking PM10 and PM2.5 frame in tunnel which incorporates with different parameters like carbon monoxide, carbon dioxide and temperature. Internet of Things is playing a major role in air quality checking framework as well. Internet of Things is mainly communicating with the various sensors, gathered and transmitted by low power ESP8266 based Node MCU. The measured parameters are easily monitored and controlled using Thing speaks Cloud.
