This paper presents the development of a solar-powered automatic irrigation system designed to minimize human intervention and optimize water usage in agriculture. The system employs a soil moisture sensor to continuously monitor the moisture content in the soil. When the moisture level drops below a predefined threshold, the sensor transmits the data to a PIC microcontroller, which in turn activates a water pump to irrigate the crops. The system ensures that only the required amount of water is supplied, maintaining optimal soil conditions for plant growth while conserving water. Powered entirely by solar energy, this setup promotes sustainable farming practices by leveraging a renewable energy source. A 4x4 keypad interface allows users to select different crop types, enabling crop-specific irrigation control. The proposed system enhances efficiency in agricultural operations, reduces the dependency on manual labor, and contributes to environmental sustainability.
