Abstract
Objective: The objective of this study is to design and implement an effective low-cost air quality monitoring system that has the ability to monitor real-time air quality over a wide geographical area. Methodology: The proposed system is developed for CO and NO2. As a test case, our developed system is deployed in Quetta city, both in static and dynamic situations and the concentration level of CO and NO2 in the air are measured and stored, along with their time, date, and location. In order to analyze this information, the stored data are then transferred to a data collection center via short-range wireless communication. Findings: Many air quality monitoring systems exits in the market; however, most of these systems have several design limitations such as size, cost, inability to move, and demand for continuous internet connectivity. Therefore, in this study, we have designed and implemented an effective low-cost air quality monitoring system that has the ability to monitor real-time air quality over a wide geographical area. Moreover, unlike existing air quality monitoring systems, the proposed system does not require any continuous internet connection and it can monitor the concentration level of pollutants in the air both in a static position and in mobile situations. The test results show that our proposed system can perform very well in both static and mobile situations. Applications: The proposed monitoring mechanism can help environmental experts and the general public to develop a more robust strategy against the adverse effects of air pollution. Keywords: Sensors, Pollution, Air-Quality, Global Positioning System (GPS), Zigbee.
Highlights
It is believed that the earth is the only planet having air and water
Indoor air pollution is caused by inefficient fuel combustion (Cooking, heating, and lighting), cleaning product usage and materials used in buildings
The concentration levels of pollutants were measured on a daily basis, 24 hours for consecutive seven days
Summary
It is believed that the earth is the only planet having air and water. Without air and water life is impossible on earth. Air pollution is one of the major problems nowadays and can affect the lives of millions [1,2]. Outdoor air pollution causes many health risks to the population living in and around urban areas. Indoor air pollution is caused by inefficient fuel combustion (Cooking, heating, and lighting), cleaning product usage and materials used in buildings (which produce chemical pollutants like radon). Air pollution causes many dangerous diseases to humans, like cancer, untimely death, lung diseases, disorders to children, damage to the respiratory system, asthma attacks, wheezing, coughing, and cardiovascular system problems [6,7]. Air pollution results in environmental degradation [8,9]
