The Solar-Powered Automatic Irrigation System is designed to automatically water crops based on soil moisture levels, using solar energy as the power source. This system helps farmers save time, water, and electricity, while ensuring proper irrigation for better crop growth.

It consists of soil moisture sensors, a water pump, and a microcontroller, all powered by solar panels with battery backup. When soil moisture drops below a set threshold, the pump turns ON, and when adequate moisture is reached, it turns OFF automatically.

Parts Used:

1. Solar Panel (12V/24V) – Provides renewable power
2. Battery & Charge Controller – Stores solar energy and regulates charging
3. Microcontroller (Arduino / PIC / ESP32) – Controls irrigation logic
4. Soil Moisture Sensor – Detects soil water level
5. Water Pump (DC Submersible/Relay-controlled) – Delivers water to crops
6. Relay Module / Motor Driver – Switches the pump ON/OFF
7. Water Pipes / Drip Irrigation Setup – Distributes water
8. LCD / IoT Dashboard (optional) – Displays moisture and pump status
