Design and development of an integrated micro grid energy management and water quality monitoring using IOT

Water is the vital natural resource and essential element in our lives. Safe and easily accessible water is critical for public health. Improved water supply and sanitation, as well as better water resource management, can boost a country’s economic growth and contribute significantly to poverty reduction. However, global water pollution is on the rise. Therefore, a technique has been introduced in order to test the quality of the water continuously. In this project, we built a solar-powered water purifier. The basic principle behind this project is reverse osmosis. This project makes use of solar energy for water purification and plant activities. The photovoltaic solar system is connected to the power grid. Solar panels, converters, and grid-connected equipment comprise a grid-connected photovoltaic system. The power for the purification unit and the entire plant is supplied by the Grid. The water quality monitoring (WQM) also has to be done effectively this can be done by using an advancing technology like Internet of Things (IoT). Water quality can be monitored using Total Dissolved Solids (TDS), Potential of Hydrogen (pH), Turbidity, and Dissolved Oxygen (DO) sensors. The sensor output values are fed into the raspberry pi as input. The obtained values are then displayed in a serial monitor connected to the raspberry pi. These values are then distinguished from the WHO (World Health Organization) standard values. Finally, all sensor data can be uploaded to the cloud and visualized.
