Water scarcity remains a significant challenge in agricultural practices, particularly in regions with erratic rainfall. Efficient water management is crucial for sustainable farming, and automation can enhance irrigation efficiency. This study presents a solar-powered irrigation system that optimizes water usage based on soil moisture levels. The system employs a moisture sensor to continuously monitor soil conditions and make real-time irrigation decisions. The integration of renewable energy ensures that the system operates efficiently while reducing dependence on conventional power sources. The irrigation system divides moisture levels into four categories: 25%, 50%, 75%, and 100%. The moisture sensor measures soil moisture content and transmits the data as voltage levels to a comparator unit. The comparator assesses the moisture levels and sends a signal to the microcontroller to determine whether irrigation is required. If the soil moisture falls below a predefined threshold, the microcontroller activates a solenoid valve via a relay, initiating irrigation. Once the soil reaches the desired moisture level, the system automatically shuts off the water supply. This automated approach ensures optimal water utilization, minimizes manual intervention and promotes sustainable agricultural practices. The use of solar energy enhances the feasibility of deployment in remote areas where power access is limited.
