How Does An Air Quality Monitoring System Work?
01
PCB Embedded or Platform
The PCB manages power, processing, and communication. It converts analogue to digital output, supports BMS (Battery Management System), and enables data logging and communication via Wi-Fi, Bluetooth, or LoRa.
02
Sensors For Air Quality Detection
Sensors detect pollutants and undergo calibration for accuracy. Automation helps them adjust to factors like temperature and humidity. Bisynking ensures multiple sensors cross-verify data for reliability.

From Sensor to Data: How Air Quality Monitors Work
03
Housing Protecting the System
The housing ensures proper sampling of air for precise readings. A perfection-oriented design reduces interference. Weatherproofing protects against environmental damage, while a robust structure ensures durability.
04
Dashboard Analyzing and Visualizing Data
The dashboard processes and displays air quality data. The backend (server) handles data storage and processing, while the frontend presents graphs, alerts, and insights for easy monitoring.
Air Pollutants, Its Sources & the Health Impacts

Particulate Matter
Sources
Indoor sources- cooking, candle burning, tobacco smoking, kerosene heaters, construction activities. Outdoor sources- forest fires, earthquakes, volcanic eruptions, power plants, waste treatment plants, oil refineries, etc.
Health Impact
PM 2.5 diameter is less than 2.5 microns and easily enters the lungs and bloodstream. It causes sneezing, inflammation, skin allergies, asthma, coughing, pneumonia, irregular heartbeat, nonfatal heart attacks, etc. A high PM 2.5 level reduces the visibility. It can also lead to environmental changes as well. PM10 causes allergies that can influence sensitive groups.

CO2
Sources
The top source of indoor presence of CO2 is humans. As humans inhale oxygen and exhale CO2. It also releases from heating devices, oil-burning coal, and gas burning. CO2 is also emitted because of Deforestation or soil degradation.
Health Impact
High CO2 levels highly influence the individuals performance in a school or office. CO2 exposure can cause headaches, dizziness, restlessness, breathing difficulty, increased heart rate, and other symptoms. CO2 emissions also cause global warming. Long-term exposure can cause extreme health issues. Such as cardiac arrest, and impaired cognitive function.

TVOC
Sources
Indoor- Paint, glue, soaps, fabrics, wood, cleansers, plastic products, solvents, etc. TVOCs vaporate at room temperature and release into the air. Outdoor sources of TVOCs are industrial processes, wildfires, and vehicle emissions.
Health Impact
TVOCs evaporate at room temperature. It causes strong odors that cause headaches, fatigue (tiredness), dizziness, nosebleeding, and eye, nose, and throat irritation. High exposure to TVOCs can cause severe health issues. Such as nausea, asthma, and damage to the kidneys, liver, or nervous system. Some chemicals can also cause cancer in animals.

HCHO
Sources
Indoor: Smoking, cleaning products, furniture, burning fuel, cosmetics, paint, incense lighting, etc. releases HCHO in the indoor air. Outdoor: HCHO releases from natural gases burning, gasoline, etc.
Health Impact
HCHO exposure can cause extreme health issues. Any individual can face irritation of the eyes, nose, and throat. It can also lead to skin or lung allergies. With it, it increases the chances of some types of cancer and also causes consciousness loss, pneumonia, and other extreme health issues. HCHO exposure can also affect reproductive health.

Types of Air Quality Monitoring
Indoor Air Quality
Indoor air quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns.
Indoor air can be 2-5 times more polluted than outdoor air. Poor indoor air quality has been linked to a range of health issues, from minor discomfort to serious respiratory conditions.

Outdoor Air Quality
Outdoor air quality refers to the condition of the air in the open environment. It is affected by a variety of factors including industrial emissions, vehicle exhaust, weather conditions, wildfires, and other natural and human activities.
Poor outdoor air quality can have significant impacts on human health, particularly for vulnerable populations such as children, the elderly, and those with pre-existing respiratory or cardiovascular conditions.
