Agriculture is one of the most water-intensive industries, and efficient water management is crucial for sustainable farming. This project presents a Smart Irrigation System based on Wireless Sensor Networks (WSNs), integrating Arduino Uno as the central microcontroller. The system employs a moisture sensor to monitor soil conditions, a DHT11 sensor to measure temperature and humidity, and a rain sensor to detect precipitation. Additionally, a wind sensor is used to assess wind speed, which can influence irrigation decisions. A 12V relay module controls the irrigation motor, and a GSM 800 module allows remote activation of the motor via SMS, enabling farmers to turn the irrigation system on or off from any location. The system also includes a temperature sensor to monitor environmental changes and a 16x2 LCD display to provide real-time status updates on sensor readings and motor operations. This automated irrigation system minimizes water wastage, optimizes irrigation schedules based on real-time environmental data, and reduces manual intervention. By leveraging IoT and WSN technologies, the proposed system contributes to precision agriculture, resource conservation, and improved crop yield.
