Description
Components
- Arduino Uno/Nano – Controls the system logic.
- Soil Moisture Sensor – Detects soil moisture levels.
- Relay Module – Switches the water pump ON/OFF.
- Water Pump – Delivers water to plants.
- Power Supply – 5V or 12V DC supply.
- LED Indicators – Show system status.
Working Principle
- The soil moisture sensor measures moisture levels in the soil.
- If the soil is dry, the Arduino triggers the relay module, turning the water pump ON.
- Once the soil reaches the required moisture level, the pump is turned OFF to prevent over watering.
- The system repeats this process continuously to maintain optimal soil moisture.
- (Optional) Data can be displayed on an LCD screen or sent via Bluetooth/IoT for remote monitoring.
