The project proposes a Health - Aware Smart water filtration system that integrates IoT - based sensors, a microcontroller, a mobile application to monitor and control water quality in real time. The system measures such as Total Dissolved Solids (TDS), pH level, turbidity, and flow rate. Unlike traditional systems, it introduces a Household Health Profiling System that allows users to select a health mode (Infant, Elderly, CKD Patient, or General Household). Based on the selected profile, the system dynamically adjusts safety thresholds. The system also provides real - time alerts and monitoring through a mobile application.
