Abstract
Clean drinking water is essential for human health since dirty water can lead to serious diseases such as diarrhoea, cholera and typhoid and long-term diseases such as kidney damage, cancer and child development problems. Though hard water is less dangerous, it causes dry skin and kidney stones and saline water causes high blood pressure. The Water Quality Monitoring System exists as a solution against existing water safety issues. The system uses an Arduino Uno as the controller and a turbidity sensor for water clarity measurement. The sensor provides readings in Nephelometric Turbidity Units (NTU), classifying water quality as clean (0–5 NTU), slightly dirty (5–50 NTU), cloudy (50–100 NTU) or heavily contaminated (above 100 NTU). The system is efficient in detecting unsafe water by sensing high turbidity readings, enabling people to take measures before consumption. The device can be highly effective for household use, rural areas, schools and water quality problem areas. Moreover, its integration into water coolers in institutions can be an effective method of performing continuous water quality monitoring, maintaining public health and safety.
