Due to the increase in vehicles and industries quality of air has gone worse and it affects living beings. Diseases like asthma and other respiratory disorders have increased even with children below the age of ten. Chimneys from industries release lots of harmful gases, though air control monitoring is established in most parts of the world. Still increasing in industries has caused a major air pollution problem. This creates the toxic atmosphere around the factories and spoils the well being of the human. With the drastic evolution in the field if the Internet of Things(IoT) it is made possible to monitor the number of toxic substances in air particles and can even control the quality of air. The objective is to develop a system which can sense the number of toxic particles in air using the MQ135 sensor. The quality of air can be controlled over the web using a dedicated server. When the toxic particles in the air like CO2, methane, alcohol, benzene increases an alarm will be triggered. Air quality in PPM is displayed on the web server when the toxicity in the air crosses the threshold value and automatically air purifier gets switched on, and it detoxifies the air. This device can be installed anywhere and can and when pollution crosses the safe region some external devices can be triggered, like displaying the alert message over the LCD display or can send the notification to all the people over there through a speaker or via SMS by using a GSMmodule.
