Indoor Air Quality (IAQ), of late, has been an increasing cause for concern due to its worrisome effects on human health. Indoor surroundings undoubtedly contain pollutants, and their presence has only increased in recent decades due to factors like constructions, furnishings, cooking fuels, personal care products, pesticides, household cleaners, and more. Multiple studies have shown time and again that we humans spend a large amount of our time indoors. Even more concerning is the fact that the ongoing COVID-19 pandemic is forcing us to stay indoors for longer than ever before. This calls for an analysis of our indoor surroundings, the silent pollutants present within, and their corresponding effects on our health. With this research work, we present an efficient, low cost and user-friendly indoor air quality monitor developed with an IoT-based sensor network coupled with the Arduino Uno. The resulting system can sense the presence of taint gases like CO, CO2, CH4, SO2, Acetone, and NH3. Sensor data is sent to the cloud, logged, and exposed to the user through interactive graphs. Alerts are provided over email to let the user know in case the optimal threshold for any of these gases is breached.
