Real Time Air and Water Quality Monitoring based on Distributed Sensor Network

Abstract

Nowadays, air and water quality are a big problem in the cities because they affect human health deeply. To determine air and water quality, the monitoring system containing a wireless sensor node having several sensors has been developed with the internet of things (IoT) technology in this study. It regularly monitors various parameters such as temperature, humidity, bar pressure, wind direction, wind speed max, wind speed average, rain fall one hour, rain fall one day, $PM_{2.5}$ and PM <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">10</inf> for air quality monitoring and consumed water, waste water, incoming water, pH sensor, conductivity sensor, turbidity sensor, dissolved oxygen and temperature sensors for water quality monitoring. To improve smart city environments, air and water quality monitoring has to be common, present everywhere, and rapidly responsive. The monitoring system based on IoT is able to track air and water pollution in real time and transmit the information fast through a wide area network. This system can be integrated with innovative approaches like smart city. Therefore, the demand for a real time monitoring system will increase day by day.
