A Logical Air Quality Monitoring System using Arduino and Smart Sensors Association

Pollution of the air is a major problem all around the globe now-a-days. Human activities and natural processes are both potential causes of air pollution. Particles and gases in the atmosphere that is harmful to human health. It affects the majority of big cities in both developing and developed countries. That's why it's so important to have a system for constant monitoring of pollution and air quality. Using a simple, low-cost sensor and an Arduino microcontroller, we were able to create an air pollution detector. The detector's benefits are its dependability, stability, quick reaction recovery, and longevity. This hardware is suitable for portable measurement and understandable data collecting; it is inexpensive, user-friendly, low-cost, and requires minimal power. It features processing software that can precisely analyze the data it has acquired. Easy air quality monitoring is made possible by straightforward equipment with practical applications in industry. This setup makes use of a number of different parts, including an Arduino Uno and a MQ135 gas sensor. When compared to its competitors, Arduino offers superior speed and compatibility. The MQ135 gas detection device is able to properly measure the amount of dangerous gases in the atmosphere and display the results in Parts Per Million (PPM).

I. Introduction

The introduction of additional undesirable biological molecules, particles, or other hazardous materials into the earth's atmosphere is known as air pollution [1]. It is a significant contributor to allergies, infections, and in rare cases, the cause of death. In addition, it damages the built environment, the ecology, and other living things like animals and food crops. If people are exposed to these poisons or chemicals for an extended length of time without protection, they can also lead to various kinds of cancer and respiratory diseases (such as asthma). For instance, due to the makeup of Carbon-Monoxide (CO) can induce severe asphyxiation, headaches and it is exposed for an extended period of time, death.
