Air Quality Monitoring Using IOT

Abstract

Air is one of the most essential tools of every human life, but for many years air pollution is a part of the world. By breathing pollutant air people are having many short- and long-term diseases, sometimes it causes immediate death. Since, people are spending most of their time in indoor area, indoor air pollution harms most to the human body and mind also. Our proposed system is indoor air quality monitoring using IoT. For experimental design we are proposing three nodes with different sensors, the system will measure the contaminant of air in real time by using low cost sensors, and measuring pollutants are Carbon Dioxide (MQ135), Carbon Monoxide (MQ7), Volatile Organic Compound (Grove-HCHO), Particulate Matter (PPD42NS, GP2Y1010AU0F), Temperature and Relative Humidity (DHT22). ESP-32 is used as development board. Every node will send contaminant measurement to a web server, where mobile and desktop user can read, and analyze the data.
