Today’s world, Internet of Things (IoT) and Remote Sensing (RS) techniques used in different area of research for monitoring, collecting and analyzing data from remote locations. Drinking water is a very precious commodity for all human beings as drinking water utilities face a lot of new challenges in real-time operation. These challenges originate because of limited water resources, growing population, ageing infrastructure etc. therefore there is a need for better methodologies to monitor the water quality. Any imbalance in water quality would severely affect the health of the humans, animals and also affect the ecological balance among species. The WHO (world health organization) estimated, in India among 77 million people is suffering due to not having safe water. WHO also estimates that 21% of diseases are related to unsafe water in India. In order to ensure the safe supply of drinking water the quality needs to be monitored in real-time. The conventional method of measuring the quality of water is to take the samples manually and send it to laboratory for analysis. This technique is time overwhelming and not economical. Also it is not feasible to take the water sample to the laboratory after every hour for measuring its quality. To overcome from these problems a new system is proposed in this work. This water quality measuring system will measure the essential qualities of water in real time. In this research work we intend to present the design and development of a low cost system for real monitoring of water quality in an IoT environment. The system consists of several sensors which are used for measuring physical and chemical parameters of water. The parameters such as temperature, pH and turbidity of the water can be measured. The measured values from the sensors can be processed by the core controller. Using this system a person can detect pollutants from a water body from anywhere in the world.
