Internet of Things (IoT) Based Real Time Water Quality Monitoring System

Abstract

Abstract: Water is an essential element for survival of human beings. Its variety of uses makes it constantly in demand. As such, it is an excellent practice to monitor its various parameters continuously to ensure it is safe for human consumption. Water quality monitoring has previously been carried out in traditional labs, which is time-consuming and prone to inaccuracies. Therefore, we need to redesign methods of monitoring quality of water. In this paper, I leverage Internet of Things (IoT) concept to design a water quality monitoring system. Water quality parameters considered are pH, Turbidity, Total Dissolved Solids (TDS), and temperature. These parameters are sensed using a Microcontroller, and sensor data is sent to the cloud with the help of a WIFI module. Android application is further developed to view stored data from the cloud. Water quality parameters are compared against WHO standards, and an alarm is issued in case of deviations
