Abstract

This paper presents the design and implementation of an IoT-based smart watering system equipped with monitoring and control capabilities using Blynk IoT software. The system integrates various components including soil moisture sensor, water flow sensor, 12V water pump motor, relay module, and NodeMCU ESP8266 microcontroller. Through this setup, users can remotely monitor soil moisture levels, control water flow to plants, and automate watering schedules via the Blynk mobile application. This paper discusses the system architecture, hardware setup, software implementation, and presents experimental results demonstrating the effectiveness and reliability of the proposed solution. Key Words: IoT, Smart watering system, remote monitoring.
