| Abstract | ABSTRACT
Efficient water management is a critical factor in achieving sustainable and high-yield coconut farming.
To present an IoT-driven irrigation monitoring and control system developed using Arduino NodeMCU
and the Blynk platform to optimize water usage and reduce manual intervention. The system incorporates
soil moisture, temperature, and humidity sensors to collect real-time environmental data, which is
transmitted via Wi-Fi to the Blynk application for monitoring and control. An automated water pump
control mechanism is integrated to initiate irrigation only when the soil moisture level falls below a
predefined threshold. The Blynk mobile interface enables farmers to remotely track field conditions,
receive alerts, and manually override irrigation when necessary. Field trials in coconut farms demonstrated
significant water savings, improved irrigation efficiency, and enhanced crop health. The proposed solution
offers a cost-effective, scalable, and user-friendly approach to precision agriculture, contributing to
resource conservation and sustainable farming practices.
Keywords: IoT, Arduino, NodeMCU, Blynk, Smart Irrigation, Precision Agriculture, Soil Moisture
