This document discusses using an Arduino system for drip irrigation. It begins with an overview of drip irrigation and its goal of placing water directly in plant root zones to minimize evaporation. The system uses an Arduino Uno microcontroller along with a moisture sensor to measure soil moisture and a flow meter to control water flow. It provides a block diagram of the components. Advantages of drip irrigation include minimizing fertilizer and nutrient loss, lessening soil erosion, and allowing use of non-potable water. The conclusion discusses how this project can help farmers irrigate more efficiently to minimize water use and pollution as supplies become scarce.
