Most conventional water tank monitoring systems focus only on water level and rely on basic LED indicators or offline displays. Many smart alternatives are expensive and still fail to track critical water quality parameters such as total dissolved solids (TDS) and turbidity. With rising environmental contamination and dependence on stored water, the lack of real-time insight into both water quantity and quality creates risks related to health, wastage, and pump misuse.
This project presents a compact, IoT-based water monitoring and control system that measures water level, TDS, and turbidity in real time while enabling remote pump control over Wi-Fi. The system logs data locally, triggers alerts when quality or level thresholds are crossed, and supports flexible deployment across single or multiple tanks. It offers a cost-effective alternative to commercial systems without sacrificing functionality.
Key Features
- Real-time monitoring of water level, TDS, and turbidity
- Wi-Fi-based dashboard for live data access and control
- Automatic pump or valve control using relay output
- Configurable threshold alerts for water quality and level
- Local data storage for review and analysis
- Compact design with support for multiple sensors and I/O expansion
Applications
- Residential overhead and underground water tanks
- Apartments and housing societies
- Industrial water storage and process tanks
- Agricultural water monitoring
- Remote or distributed water storage systems requiring quality checks
This IoT water monitoring system demonstrates how combining sensing, connectivity, and control can significantly improve water management without increasing system complexity or cost. By integrating level detection with real-time quality monitoring, the design addresses both availability and safety concerns in stored water systems. The project also shows how a single compact controller can handle sensing, networking, data visualisation, and control tasks reliably, making it suitable for scalable deployments and long-term installations
