Water Monitoring Using Internet of Things

Water is one of the most important key substances on earth. The existence of the human race depends on it. Though 71% area of the earth is covered by water, only 0.3% is usable by humans, which makes it more precious than any other substance. Not only for drinking but also for agriculture, fisheries, and all other sectors, quality of water is essential. However, for the past few years, the quality of usable water has been decreasing at an alarming rate, so it has become a vital issue to monitor and analyze the water quality of our surroundings to avoid a catastrophic disaster. This paper proposes an IoT-based water pollution monitoring system that provides a comparison and reports about water quality and pollution using different parameters. The system inputs the temperature, pH, and turbidity from the water using sensors and stores the value in a cloud database with a microcontroller. Then, after processing those data from the cloud and comparing them with the standard value, quality and pollution rate can be monitored with any internet-connected device such as a smartphone or laptop. As an IoT-based system, it is quite cost-effective and an easy-to-use method. So, the proposed system can be significantly beneficial to our society.
