Development of Internet of Things (IoT) Based by Using Blynk for Irrigation and Fertigation System

Abstract

Urban agriculture provides innovative solutions to meet the growing demand for sustainable food production in areas with limited ground availability, particularly in densely populated urban regions. A significant challenge for urban gardeners and plant enthusiasts is maintaining plant health during prolonged absences, often resulting in dehydration and plant loss. This research introduces a smart irrigation system designed to automate plant care and enhance convenience. The system incorporates a soil moisture sensor, a liquid ultrasonic sensor, and the Blynk application for efficient monitoring and management of irrigation processes. Inventor software was used to design the system, construct circuits, and develop an intuitive application interface. The system operates autonomously, watering plants when low soil moisture is detected, while also enabling users to manually activate irrigation via a mobile application during extreme weather conditions or emergencies. Real-time data on soil moisture and water levels are transmitted to the user’s mobile device through the internet, ensuring seamless remote control and monitoring. The methodology involved integrating hardware and software components, calibrating the system, and conducting performance evaluations to validate its reliability. Experimental results demonstrated the system’s capability to maintain optimal plant health by addressing dehydration risks effectively. This research offers a practical, efficient, and user-friendly solution for urban gardeners, contributing to the development of innovative and sustainable urban agriculture practices. By addressing key challenges associated with plant care in restricted environments, the system could promote convenience, reliability, and improved plant vitality in modern living spaces, advancing the potential for smart urban farming solutions.
