💧 Water Quality Checker

A Fuzzy Logic–based system to assess and classify water quality using key parameters such as pH, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Nitrate, and Temperature.
The system provides an intuitive way to evaluate water quality without relying on exact thresholds, making it more adaptive to real-world variations.
