There are three techniques for the control of indoor air pollutants dilution, extraction and source control. The following are additive control to reduce the indoor air pollutants:
most essential conditions for any ménage or assiduity to give comfort and better air quality. Air quality is a measure of how clean or weakened air can be which is bad for our health and health of the terrain. Air quality is measured according to the situations of different feasts present in the atmosphere. Detector grounded air quality regulator is used to measure the situations of colorful feasts using the MQ- 135 detector and allows us to maintain the air quality in the handed atmosphere. It helps us to not only maintain the air quality, it also enables us to remove the bank produced by burning incense sticks, cigarettes etc., The detector senses and monitors the quantum of feasts present in the room and sends the information to the Internet of effects( IOT) which controls the suckers present in the room. This sucker pumps out the old air from the room and pump in the fresh air from the outside terrain and also ensures to maintain the same temperature in the room. Then, IoT is used to give the information about the situations of feasts present in the room to the stoner via the android grounded operation which is developed with the help of MIT app innovator. The primary end of this system is to give and maintain a common standard of high inner air quality and a productive and comfortable place of work for all the people inside the room.
Elimination, removal substitution at the source Filtration and cleaning of contaminants Indoor ventilation Encapsulation or interfering with the material ability to give of air pollutants Isolation by space distance or time of use of potential contaminant Awareness to the building of occupant’s operations under maintenance personnel
Indoor air quality is affected due to the factors since, the building fabric, furnishings and equipment, occupants and their activities produce pollution. In an inactive building, some of these air pollutants may have directly exhausted to the outdoors and remaining will be removed as the outdoor air enters the building and replaces the air inside. The installation of the air conditioning system with filtration unit enormously reduces the microbes, air pollutants and dust particles in the outside air. The adaptive ventilation system has to be designed for maintaining the indoor air quality enhancing better air exchange between indoor and outdoor. This project concentrates on the development of IoT based Smart Air Quality Monitoring System to remove the hazardous particles by continuous monitoring and improving the exchange of indoor-outdoor airflow.

1. INTRODUCTION Proper ventilation is the most essential requirement for any room and hence the ventilation system has to be designed properly. The Fig. 1.1 shows that the ventilation system is designed in such a way to prevent contaminants and aids in removing contaminants from the interior source. A ventilation system has several key components including contaminant source, an exhaust hood, air mover, ducts and Fittings, makeup air exhaust, air pollutants removal device, discharge stack and air re-circulation.
1.2 PROBLEM DEFINITION The major problems in any air conditioning system installed for indoor air regulation are better in providing the thermal comfort than maintaining indoor air quality. The air conditioned indoor due to improper maintenance and poor ventilation system causes serious health issues. This project aims to provide improve airflow rate enhancing ventilation during presence of toxic gases, hazardous smoke and dust particles. Developing a portable IoT based Air quality monitoring sensor devices along with smart phone application to alert user during hazardous exposure and air quality status in real time.
