Water quality is a vital factor influencing human health, industrial productivity, and agricultural yield. Hard water, containing high concentrations of dissolved minerals such as calcium and magnesium, causes scaling in pipelines, reduces the efficiency and lifespan of household appliances, and increases soap consumption. Traditional water softening systems often lack continuous monitoring and automated control, leading to inefficient operation, excessive resource consumption, and unpredictable water quality. This project proposes the design and development of a Hard Water Softener with Automated Quality Monitoring, capable of real-time measurement of pH, Total Dissolved Solids (TDS), and specific mineral concentrations. The system integrates an ion-exchange resin softening unit with an array of digital water quality sensors. These sensors feed continuous data to a microcontroller-based control unit, which analyzes the parameters and automatically activates or regulates the softening process as per predefined thresholds. The monitoring system is complemented by an LCD display and IoT- enabled remote access, allowing users to track water quality trends and system performance from anywhere.
