Water Quality Monitoring System Based On IOT

Abstract

Different diseases are caused due to the consumption of contaminated water. It is of utmost importance that monitors the quality of water used for domestic purpose. This proposed system presents an IoT based warning system that regularly monitors the quality based on the parameters like pH, turbidity, and conductivity. A tank was devised to integrate the sensors and connected to the main source of water supply for buildings. The real time measurements of these parameters could be viewed on a mobile application along with a user-friendly warning indications. Testing was done with water samples that have been procured from various sources and the accuracy of the system was validated with lab tests. The main advantage of this system is that it incorporates low cost platforms and cloud storage that remains portable, easy for maintenance, good accuracy, and incorporated near to consumer.

Existing System

The system used a microcontroller and multiple sensors to measure the quality of water such as PH, turbidity, conductivity, total dissolved solid and temperature. LCD screen used for displaying quality parameter values at the site and send a warning message to mobile phone via SMS.

Proposed System

The essential parameters chosen for monitoring the quality of water were pH, turbidity and conductivity. The parameters had different values when procured from different water sources. The acidity or alkalinity of any substance is called pH, which is represented as a value ranging from 0 to 14. Turbidity is another main parameter to check the water quality. Turbid water will no longer be transparent since particulates are present in it. Next parameter is conductivity, which is a measure of water’s capability to pass electricity.
