An Exploratory Approach to Monitor the Quality of Supply-Water Through IoT Technology

摘要

An IoT based design for monitoring the quality of supply-water is represented in this paper. The sensor-based circuitry is completely powered up with solar energy which is a sustainable approach as well. Through this designed system using Arduino Mega 2560, different qualitative parameters of water namely, the pH level, turbidity, salinity, arsenic level etc. can be measured by simple modification but for implementation purpose only the pH level and turbidity of water have been measured using sensors. However, the information gathered from the sensors are sent to the cloud server by means of a WiFi module. The collected data is further analyzed, is shown in visual format in LCD and graphical comprehension is demonstrated via `ThingSpeak', a cloud server. The circuit is also modified to control the water pump for decreasing the wastage of water and hence electricity usage. The designed system can be utilized not only to the rooftop tank but also to overhead water tanks for monitoring the quality of water easily and from anywhere in the world through internet.
