Abstract

The Internet of Things (IoT) technology offers great potential in the agricultural sector, especially in the automation of plant irrigation systems. Many farmers face challenges with water use efficiency and real-time land condition monitoring. Manual irrigation systems often lead to wa-ter wastage. Currently, many centralized irrigation systems use a one-by-one watering approach, requiring multiple sensors to monitor each plant's condition, making them less efficient. To address this issue, this research developed an automated irrigation system controlled by Node-REDand ro-botic technology. The system is designed to require only one sensor to monitor the entire agricul-tural area, while still efficiently distributing water to many plants. Node-REDmanages data from soil moisture and environmental temperature sensors, then activates the watering robot to distrib-ute water according to the plants' needs. The system was tested by comparing manual and auto-matic methods using polybags. The soil moisture sensor sends data to Node-RED, which activates the watering robot when soil moisture falls below a set threshold. Test results show that the auto-mated system can save up to 20% of water usage compared to manual methods, while keeping soil moisture within the optimal range. This systemalso enables real-time monitoring and control, providing a more efficient, timely, and resource-saving solution.
