IOT INTEGRATED SOLAR POWERED SMART HYDROPONICS SYSTEM FOR SUSTAINABLE INDOOR AGRICULTURE

As the demand for eco-friendly agricultural solutions grows, hydroponics offers a modern approach to farming that eliminates the need for soil while significantly conserving water and nutrients.This research presents a compact, solar-powered smart hydroponic system integrated with IoT capabilities, specifically designed for indoor environments.The setup incorporates an ESP32 microcontroller at its core, managing real-time data acquisition and automated decision-making processes.Essential components include a suite of sensors that track environmental and system parameters such as temperature, humidity, water reservoir levels, and nutrient concentrations.A 16x2 LCD provides onsite feedback, while a buzzer alerts users to critical system changes.The irrigation system is operated by an AC water pump, which functions in two modes: Manual mode allows remote activation via an IoT dashboard, whereas Automatic mode relies on sensor thresholds to maintain optimal growth conditions autonomously.All system data is uploaded to a cloud-based IoT platform, enabling remote observation, logging, and analysis.Powered entirely by solar panels, the system reduces energy consumption and supports sustainable indoor agriculture.The automation of irrigation and environmental control reduces labor, ensures optimal plant health, and supports continuous food production in space-limited areas.This innovation highlights a practical and scalable solution for urban farming and smart agriculture.
