Project Summary

This system using IoT technology have performed real-time monitoring to detect different types of atmospheric pollutant concentrations. This module can reduce both power consumption and the cost of the device efficiently. Furthermore, the combination of the sensors and processor together with its low power consumption allows the system to collect data for certain periods. This project serves the purpose since We not only don’t require air, but also we require clean pollution free air for our survival. The data collected from air quality monitoring helps us assess impacts caused by poor air quality on public health; determine if an area is meeting the air quality standards; identify polluted areas, the level of pollution and air quality level also based upon the data collected control measures can be devised for protection of environment and health of all living organisms.

? Air quality data act as metrics to implement and evaluate new traffic management policies. By deploying air quality monitors along busy roads and intersections, cities can track pollution trends and hotspots - the routes and times of the day with the highest concentration of pollutants - to refine their policies accordingly. The widespread commercialization of high-density air monitoring networks and personal air monitoring gadgets is leading to new possibilities in public health. Air pollution exposure, even in the short term, lowers productivity and puts strain on our physical and mental health. Combined with improvements in access and education, everyone can capitalize on localized air quality data to take appropriate preventative and mitigative actions to maximize their quality of life.

? Children are one of the groups most vulnerable to air pollution; they are more susceptible to the unpleasant effects of toxic pollutants that can adversely affect school performance and which can increase the risk of developing respiratory and cardiovascular complications. The addition of real-time air quality monitors in schools helps educators make responsible choices to nurture healthy environments and give parents peace of mind.

? As countries move to cleaner energy portfolios, the resulting decrease in greenhouse gas emissions is also addressing some of the largest air pollution concerns in the world. Air quality data is helping validate environmental co-benefits, serving as a proxy to measure climate change impact and the effectiveness of related policies. Moreover, the actions of industry have a huge impact on the health of employees and neighboring communities. Real-time air quality data helps big polluters work within their corporate responsibility team or to partner with local environmental authorities to design appropriate emissions cutback initiatives.

Project Objectives

The level of pollution has increased with times due to lot of factors like the increase in population, increased vehicle use, industrialization and urbanization which results in harmful effects on human well-being by directly affecting health of population exposed to it. According to the United States Environmental Protection Agency (EPA), indoor air is 100 times more contaminated than outside air. Most modern populations spend 80 to 90 percent of their time indoors; therefore, indoor air has a greater direct impact on human health than outside air. Moreover, in contrast to atmospheric pollution, indoor pollutants are about 1000 times more likely to be transmitted to the lungs, causing diseases such as sick building syndrome, multiple chemical sensitivities, and dizziness. Indoor air quality management is very important, as it can prevent exposure through proactive precautionary measures .Therefore, efficient and effective monitoring of indoor air is necessary to properly manage air quality. So we propose an IoT based Air Pollution Monitoring & Alert System that allows us to monitor and check live air quality in an area through IOT. We will restrict the air quality monitoring system within indoors. System uses air sensors to sense presence of harmful gases/compounds in the air like NH3,NOx, alcohol, Benzene, smoke,CO2, etc. and will trigger alarm when the air quality goes down beyond a certain level by using certain hardware components we will be able to tell the quality of air free from potentially harmful chemicals and pollutants and constantly transmit this data. The sensors interact with arduino uno which processes this data and transmits it over the web server. This allows authorities to monitor air pollution in different areas and act against it.

So the objective/perspective behind the system is to develop a reliable, economic and userfriendly decision support system, to provide an available system 24/7 & analyze the results more clearly and to establish a system to provide air quality/pollution information continuously.

Project Implementation Method

This project will contain both hardware as well as software systems. 

• In hardware, the components include Arduino UNO, NodeMCU-ESP8266, and MQ-135 etc.

• Upload the code to Arduino, sensors are also initialized.

• Scanning and connecting to the Wi-Fi Hotspot.

• Results will be obtained through sensors.

• AQI Level is displayed on LCD, and buzzer and LED Lights also work based on AQI Level.

• If ppm will be below 130, the result and normal status will be shown on LCD display as well as on web. No LEDs or buzzer will work in this scenario. 

• If ppm will be between 130 and 250, the result and status of medium will be shown on LCD display as well as on web. Green LED will be on. No red LED or buzzer will work in this scenario. 

• If ppm will be greater than 250, the result and status of Danger will be shown on LCD display as well as on web. Red LED and buzzer will be on. Green LED will not work in this scenario. 

• Results can be plotted using Serial Plotter in Arduino IDE.

• Other software tool include ThingSpeak to view the webserver. ThingSpeak enables sensors, instruments, and websites to send data to the cloud where it is stored in either a private or a public channel. 

• PPM will be calculated Parts per million (PPM) is a unit of measurement used when expressing a very dilute concentration level of pollutants in the air, water and other fluids.

Benefits of the Project

The right to aspire in clean air is of all living beings however due to development by the mankind in various sectors has efficiently contributed or one can say is solely responsible for polluting the environment. Out of which one of the ways is by deteriorating the air quality by introducing harmful particles which are nevertheless of many kinds. Moving ahead, it’s a dire thing to keep a monitoring system to check the air quality otherwise the detrimental effects o poor or one can say harmful air quality can lead to the advent of numerous infections and diseases or even premature deaths. Therefore for this system the intended audience is almost everyone that breathes however it needs to be installed at certain places so for that it may be at schools or kindergartens where the air quality would be constantly checked and it will then be improved accordingly as a clean fresh environment contribute to higher productivity and health benefits and same goes for offices. Poor indoor air quality in the workplace can contribute to decreased productivity, absenteeism, and even possible litigation. By effectively monitoring indoor air quality, employers are able to ensure workers can enjoy healthier spaces with cleaner air, free from potentially harmful chemicals and pollutants. As a result, employers report higher retention levels, increased productivity, and a reduction in absenteeism.

Indoor air pollution carries significant short and long-term health risks for inhabitants. Typical symptoms associated with poor indoor air quality include eye, nose, and throat irritation, headache, nausea, dizziness, and fatigue. In some cases, exposure to indoor air pollution can lead to acute and chronic respiratory illnesses, including asthma, lung cancer, pneumonia, systemic hypertension, chronic obstructive pulmonary disease (COPD), Legionnaires’ disease, and humidifier fever. Therefore it needs to be installed anywhere like malls, airport lounges, cafes, car-parking lots, hospitals, canteens, labs etc.Therefore, improving air quality can deliver substantial health benefits; reducing air pollution levels means reducing premature deaths and diseases from stroke, heart disease, lung cancer, and both chronic and acute respiratory diseases, including asthma. the most harmful air pollutant.
