Smart Air Purifier with Air Quality Monitoring System Atharv Bharaswadkar1, Deep Mehta2 Dept. of Mechanical Engineering, Marathwada Mitra Mandal’s College of Engineering, Pune ---------------------------------------------------------------------***--------------------------------------------------------------------2) By referring to a publication [2], we learned a basic ABSTRACT - The project introduces the concept and
method for creating an air purification system that uses an Arduino and a dust sensor.
physical model of an air purification system for modest public spaces or residences. The model is equipped with a set of sensors and an Arduino UNO series microcontroller that are used to determine the air quality. As the LCD system senses the quality of the air in the room, as well as the temperature and relative humidity, it displays live air quality index, temperature, and relative humidity. The air purifier's body is made of transparent glass sheets and filters. Activated carbon and HEPA filters are used as filters. It also includes a UV-C lamp to kill harmful viruses.

5) We used a patent that described the operation of an air filter to gain insight into how an industrial air filter was actually built. [5]
1. INTRODUCTION An air purifier is a device that cleans the air in a room. These devices are commonly used to improve the air quality in homes, offices, and other indoor spaces. Air purifiers remove pollutants from the air by drawing it in from the surrounding environment and passing it through a series of filters. The purified air is then restored to the room.
6) The study [6] provided a thorough explanation of a Shop Air Filter plan and its design.
3. DESIGN AND WORKING: 3.1 THE STEPS FOR FILTERING AIR ARE AS FOLLOWS:
The proposed air purifier removes particles from the air with HEPA filters, whereas others on the market remove gasses and odors with activated carbon filters. Some air purifiers are intended for particular rooms or spaces, such as kitchens or bedrooms, whereas others are portable and can be used in any indoor space.
1) Air is drawn into the air purifier's first filter through an aperture in the front panel. 2) The first filter is referred to as the "Dust Filter" and its primary job is to filter out the large airborne particles. It eliminates 3 to 10 micron-sized contaminants.
2. LITERATURE SURVEY:
3) The second filter is the so-called "Pre Filter," and its primary job is to remove particles in the air that are visible to the unaided eye, including hairs. It eliminates particles between 10 and 25 microns in size.
Large urban areas with high air pollution have negative effects on both people and the environment. Indian environmental problems are getting worse quickly. Vehicles and industries, which contribute to a variety of respiratory illnesses like asthma and sinusitis, are the main sources of air pollution. Due to the quantity of carbon dioxide and other dangerous chemicals released by vehicles and industries, the air quality is poor in major cities like Kolkata, Delhi, and Mumbai. In the References section, you can find examples of references from many categories, such as:
4) The Fine filter eliminates the majority of particles with a diameter larger than or equal to 3 microns. 3.2 CIRCUITS: A) Sensors NH3, NOx, alcohol, benzene, smoke, and CO2 are just a few of the gasses that the MQ 135 air quality sensor can detect. Perfect for usage in a factory or office. The MQ135 gas sensor is very sensitive to hazardous gasses like smoke and ammonia, sulfide, and benzo steam. It is inexpensive and especially useful for applications involving the monitoring of air quality
1) Based on the information provided in the paper[1], we have extracted sensor values from the MQ135 sensor and have a rough idea of how to construct our air monitoring system using wireless sensor networks.
