Water Quality Identification System Using Arduino

Water is one of the main resources for humans and animals in their daily life. On average every human drink 4 to 5 liters of water per day. Drinking plenty of water can avoid many problems that they face in their daily life like kidney stones, Extra weight, … etc. Many of the rural area people and schools are not aware of the quality levels of water and their quality parameter values, by this they are taking the water that is available in their surrounding or storing. The government provided water which in some areas may not filter the water properly and drinking such impure water many people in rural are affected to diseases. Through this system, users can know whether the water is drinkable or not. In this module, the system consists of three sensors and a display which is included in a bottle and a display placed outside of the bottle which shows quality status of the water and which is safe for drinking or not. When we pour a sample of water in the bottle the sensors provide respective PH value, Chlorine value, Turbidity value and the values are displayed in the display along with the statement whether the water is safe or unsafe.
