Abstract: The integration of Internet of Things (IoT) technologies has transformed modern agriculture by offering automation, accurate control, and remote monitoring. This work introduces an IoT-enabled hydroponic monitoring and management system that enhances the efficiency and sustainability of soilless cultivation. The system utilizes an ESP32 microcontroller with built-in Wi-Fi to link to the Blynk IoT platform, facilitating live tracking and control through a mobile interface. Core environmental parameters such as moisture and pH are continuously measured using appropriate sensors. The collected data are processed by the ESP32 and transmitted to the Blynk application, where users can view real-time readings and perform necessary adjustments. A relay-based circuit automatically manages water and nutrient pumps to ensure timely and precise delivery to plants. This reduces manual intervention, conserves resources, and maintains stable growth conditions. The proposed system provides a low-cost, scalable, and user-friendly solution suitable for home gardening, academic experiments, and commercial hydroponic farms, contributing to sustainable and productive agriculture.
