Abstract

The solar-powered hydroponic system integrated with the Blynk app represents a significant advancement in modern agriculture by combining renewable energy, precision farming, and IoT technology. Utilizing the Nutrient Film Technique (NFT), the system efficiently circulates nutrient-rich water over plant roots, ensuring optimal growth without the need for soil. Powered by solar energy, it reduces environmental impact and operational costs while maintaining uninterrupted operation through efficient energy management. The ESP32 microcontroller and integrated sensors monitor key parameters such as pH, TDS, temperature, and water levels, with real-time data accessible via the Blynk app for remote monitoring and control. Over seven days of evaluation, the system demonstrated reliability, maintaining stable conditions for lettuce cultivation with consistent growth and energy efficiency. This innovative approach addresses challenges like water conservation, food security, and sustainability, making it a viable solution for small to medium-scale urban farming while contributing to environmental resilience and global food security.
