An automatic drip irrigation system powered by an Arduino UNO microcontroller is proposed in this work. It utilizes both a soil moisture sensor and a water pump to water the plants. The system can be programmed to water the plants at specific times or whenever there is a change in the soil moisture level. It saves water, guarantees proper watering, minimizes evaporation and runoff, and is both cost-effective and easy to build. The system can be tailored to meet the specific needs of different plants and growing conditions. This project is a simple example of how automation can be used to improve irrigation system efficiency and save resources.
