IoT-Driven Arduino Nodemcu Irrigation Monitoring and Control System for Coconut Farming With Blynk

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.
