A. Amala, Dr. P. Anil Kumar, Khusboo Solanki, Srinesh Goud E, Rahul S V, Ganji Nikhil 02 07 As the demand for ecofriendly 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 solarpowered smart hydroponic system integrated with IoT capabilities specifically designed for indoor environments The setup incorporates an ESP32 microcontroller at its core managing realtime data acquisition and automated decisionmaking processesEssential 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 autonomouslyAll system data is uploaded to a cloudbased 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 spacelimited areas This innovation highlights a practical and scalable solution for urban farming and smart agriculture Copyright (c) Journal of Science Engineering Technology and Management Science.
