Real Time Indoor Air Quality Monitoring System

Abstract: Major of the time about 2/3rdof the day we humans spend indoor. So it is necessary to keep our indoor environment clean and healthy. As air quality has major influence on the health of people so this A Wi-Fi Based, Multi-Sensor, Real Time Indoor Air Quality Monitoring System is proposed. The system will detect the level of the several gases like Carbon Dioxide (CO2), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), and Volatile Organic Compound (VOC) and also the presence of dust, temperature, and humidity. The system will alert the user if levels of these gases are exceeded through Wi-Fi module on their smartphones. The system consists of Arduino platform and multiple sensors along with Wi-Fi and Bluetooth module. The Wi-Fi module is used to communicate with the user.
