Abstract: With the growing demand for sustainable and space-efficient farming methods, hydroponics has emerged as a promising alternative to traditional soil-based agriculture. It allows plants to grow faster and healthier by providing nutrients directly through water solutions, reducing the need for large farmland and excessive water usage. The Smart Hydroponic System is designed to automate and optimize plant growth in a controlled environment using Arduino-based monitoring and control. The system integrates sensors such as DHT11, water level, TDS, and turbidity sensors to track temperature, humidity, nutrient levels, and solution quality. An air pump ensures root oxygenation, while a flexible lighting setup supports plant growth. Voice alerts and scheduled music playback via the APR33A3 module enhance interactivity, with real-time data displayed on a 16×2 LCD. This compact 2-foot model demonstrates an efficient, low-cost solution for sustainable, soil-less cultivation.

Keywords: Smart Agriculture, Remote Monitoring, Sustainable Farming.
