The integration of Internet of Things (IoT) technology into agriculture has the potential to significantly enhance productivity, resource management, and sustainability. This paper presents an IoT-based agriculture system utilizing the Node MCU platform, which leverages its Wi-Fi capabilities and ease of programming to create a cost-effective, scalable solution for modern farming. The proposed system consists of a network of sensors and actuators to monitor and manage key environmental parameters such as soil moisture, temperature, humidity, and light intensity. Data collected by the sensors is transmitted in real-time to a cloud-based server via the Node MCU, where it is processed and analyzed to inform decision-making processes. Actuators are employed to automate irrigation and other critical agricultural activities based on sensor feedback, thereby optimizing water usage and improving crop health. This system also includes a user-friendly interface that allows farmers to remotely monitor field conditions and control the actuators using a smartphone or computer. The implementation of the Node MCU-based IoT system demonstrates significant improvements in operational efficiency, resource conservation, and crop yield, highlighting its potential as a vital tool for the advancement of smart agriculture.
