Clean drinking water is the most valuable resource for humans. Any imbalance in the water quality would seriously affect the health condition of the humans. Now a day?s drinking water utilities are facing various challenges in real time due to limited water resources, global warming, growing population, and pollution. Hence there is a need for better methodologies for real-time water quality monitoring.

As the recent survey of WHO estimated that in India 77 million people face problems due to unsafe drinking water and 21% of the diseases are related to impure water. WHO also estimated that 1600 people die every day in India due to diarrhea? The conventional method of water quality monitoring involves the manual collection of the water at different areas and this water is tested in the laboratory.


????????? In the existing System, we monitor the water quality by connecting the PH sensor, conductivity sensor and turbidity sensor which is collected in Nodemcu and uploaded over the Cloud for analysis.


In the proposed system same setup, we have from the Existing system but we have to add turbidity, Flow sensor and Temperature sensor and valve. Purpose of using the flow sensor is to find out how much water is consumed by each house. And solenoid valve is to Automatic Closing of the pipe. This whole system will act as water quality system.
