This project proposes a smart automated water management and irrigation system controlled by an ESP32 module, enabling efficient resource utilization and real-time monitoring. The system consists of a central water tank equipped with a water-level sensor and a pH sensor, whose readings are continuously processed by the ESP32. Two pumps are used: Pump 1 supplies water to the toilet flush tank, while Pump 2 irrigates plants. A flush-usage detection mechanism increments a digital flush count each time the flush is activated, ensuring accurate tracking of water consumption. For irrigation control, a soil moisture sensor monitors the moisture level and automatically triggers Pump 2 when the soil becomes dry using Relay. All sensor data—including flush count, soil moisture percentage, water level, and pH value—are displayed on both an onboard LCD screen and a web interface hosted by the ESP32, enabling remote monitoring through Wi-Fi. The ESP32 executes decision-based logic to control pump operation and ensure optimal water distribution without manual intervention. This integrated smart water management system enhances usability, minimizes water wastage, and supports sustainable domestic and agricultural water usage through automation and IoT-based monitoring.  

The objectives of the project include:

 To design and implement an ESP32-based smart water management and irrigation system capable of autonomous operation with real-time monitoring.

 To measure and monitor key water parameters such as

• Water Level
• pH Level
• Soil Moisture
• Flush Count

 To automate water distribution using pumps, were

• Pump 1 refills the toilet flush tank when flush usage is detected
• Pump 2 irrigates plants when soil moisture is below the threshold

 To display all real-time sensor readings on an LCD module, enabling easy on-site monitoring.

 To develop a web dashboard using the ESP32’s Wi-Fi capability for remote visualization of water level, soil moisture, pH value, and flush count.

 To reduce water wastage by enabling intelligent decision-making based on sensor data and automated pump control.

 To ensure system reliability and safety through continuous monitoring and timely activation of pumps only when required.

 To create a scalable and user-friendly smart water management solution suitable for homes, farms, or greenhouse applications.
