Air pollution monitoring system using wireless sensor network (WSN)

Abstract

Rapid industrialization and urbanization cause the continuous decline in the environmental quality parameters. Today, the world is facing a challenge like global warming which occurs when carbon dioxide (CO2) and other greenhouse gases accumulate in the atmosphere and absorb sunlight and solar emission that have bounced off the earth’s surface. Its impacts are sea level rise, changes in the seasonal patterns, rising temperature, more frequent droughts, and extreme rainfalls. Air pollutions’ serious impact on human health and environment requires worldwide awareness and understanding. Existing systems gives real-time air pollution data to pollution monitoring authorities and, these systems are having fixed infrastructure with maintenance, reconfiguration, and reduced sensing issues. Conventional measurements are costly methods and spatially restricted. Therefore, air pollution monitoring becomes a challenging task. Here, we propose Wireless Sensor Network (WSN) based system with low-cost sensors, which collects air pollutant information in real time from different locations. Sensor data is transferred to cloud (ThingSpeak an open source API) for future analysis and calculate Air Quality Index (AQI) Android application can be used to visualize real-time air quality of the location.
