Air Quality Monitoring System Using Arduino and Matlab Analysis

This paper presents an air quality monitoring system using Matlab. For all living things, the air is the foremost important aspect. Measuring air quality is vital in raising awareness about the importance of caring for future generations and living a healthier lifestyle. When people with health problems such as lung disease, nonfatal heart attacks, irregular heartbeat, and worsened asthma breathe in the bad air quality, it will affect more in their health. People have difficulty detecting poor air quality since they only perceive it after inhaling it. Carbon monoxide poisoning from fireplaces and cooking stoves can cause weariness, decreased vision, and chest pain. This paper aims to study the real-time communication between Arduino UNO and Matlab and analyze the air quality at a specific place. The main component used are Arduino UNO, MQ7 carbon monoxide sensor, and MQ135 air quality sensor. An additional buzzer and LED are attached to the system to alert the user if the air quality is at a harmful level. Overall, the results displayed by Arduino are almost similar to those indicated in Matlab.
