An IoT is a smart sensor device that is able to sense, connect, and communicate with their surroundings as well as with other users and systems. Global air pollution is one of the major problems of our day and an increase in pollution levels over time has been caused by a number of factors, including population growth, increased vehicle use, industrialization, and urbanization. These factors have a detrimental effect on public health and well-being, when the air contains a sufficient amount of harmful gases, such as ammonia, sulfur dioxide, nitrogen dioxide, smoke, and carbon monoxide. In order to analyze the quality of the air through an internet server, we are developing a pollution monitoring system based on the Internet of Things. The sensitivity and precision of the current monitoring methods are low, and they require laboratory analysis. To address the shortcomings of the current setup, we propose a three-phase pollution monitoring method. The webpage will show the air quality in PPM to make monitoring easier for us. The system monitors the air quality using the MQ2 and MQ7 sensors. It lacks sensitivity and accuracy, but it can identify dangerous gases and measure their quantity with precision. We suggest a three-phase pollution monitoring system to address the shortcomings of the current configuration. To help us with monitoring, the portal will display the air quality in parts per million. Using a computer or a mobile device, you can monitor the pollution level project at any time and from any location, by deciding to proceed our activity or journey. Also we can control the pollution level using different algorithmic methods. Here MQ2 and MQ7 sensors are used by the system to track the quality of the air. It counts the number of hazardous gases it finds with accuracy and proceed for the processing to control pollution.
