Real-time water quality monitoring using Internet of Things in SCADA

Abstract

Water pollution is the root cause for many diseases in the world. It is necessary to measure water quality using sensors for prevention of water pollution. However, the related works remain the problems of communication, mobility, scalability, and accuracy. In this paper, we propose a new Supervisory Control and Data Acquisition (SCADA) system that integrates with the Internet of Things (IoT) technology for real-time water quality monitoring. It aims to determine the contamination of water, leakage in pipeline, and also automatic measure of parameters (such as temperature sensor, flow sensor, color sensor) in real time using Arduino Atmega 368 using Global System for Mobile Communication (GSM) module. The system is applied in the Tirunelveli Corporation (Metro city of Tamilnadu state, India) for automatic capturing of sensor data (pressure, pH, level, and energy sensors). SCADA system is fine-tuned with additional sensors and reduced cost. The results show that the proposed system outperforms the existing ones and produces better results. SCADA captures the real-time accurate sensor values of flow, temperature, and color and turbidity through the GSM communication.

Recent Advances in Information and Communications Technology (ICT) and Sensor Technology for Monitoring Water Quality

“…The use of web-based data storing and processing with the Internet has recently increased with the usage of sensor data [5,115]. Various technologies related to the Internet of Things (IoTs) are applied for remote sensing and the management of measured data [116,117]. The easy accessibility and use of open-source programming languages (e.g., R or Python) enable advanced analysis of data with high data processing technologies, such as machine learning [5,118].…”

IoT Based Flow Valve Control and Accounting System

“…Of cloud that information will be monitored by the Water Monitoring Board (WMT) to find whether water can be used for drinking purpose or not and data examined will be uploaded to public domain for public reference. In [6], in many parts of the world the main reason for disease causing is water pollution water pollution ,and theft of water using temperature sensor pH sensor flow sensor .All these sensors are coordinate integrated in Arduino board using GSM component these system can be well tuned and it will be cost efficient and can be implemented by anyone. In [7], it notifies the real-time parameter of water on using certain physical and chemical factors of water quality such as temperature, pH, conductivity, movement and rusting-decrease potential.…”

On the Use of an IoT Integrated System for Water Quality Monitoring and Management in Wastewater Treatment Plants

“…In this sense, the work presented by Geetha [24] is based on the single-chip TI CC3200 microcontroller to monitor pH, conductivity, water level and turbidity and upload them to the Ubidots cloud. Reference [45] is based on Arduino to monitor pH, conductivity and dissolved oxygen and upload them to the ThingSpeak cloud, whereas the work presented by Saravanan [46] is based on Arduino to monitor flow, temperature, color, and turbidity, and upload them to the SWQMS cloud server. However, the prototypes cited previously are far from the close-to-market stage.…”
