Smart Irrigation System Using Soil Moisture Sensing and Arduino Automation

---

Abstract

With the combination of real-time soil moisture, the Smart Water Irrigation System is an automated irrigation system based on a microcontroller that effectively supplies water to plants. Using a submersible pump, an Arduino microcontroller, a relay module, and a soil moisture sensor, the system senses and reacts to the water need of the plants. To make sure that there is maximum irrigation with minimum human interaction, the sensor checks soil moisture levels and activates when the levels decrease below a set threshold. The Arduino activates the pump to irrigate the soil. This study not only shows the affordability and usability of automation in home gardening and agriculture but also the potential of automation in tackling global issues such as environmental sustainability, water shortages, and wasteful irrigation. The system is scalable and flexible, and a giant leap towards intelligent environmental management and precision agriculture.
