Project title: An Efficient and Cost Effective IoT-Based Watering System for Home Gardening

Abstract—Urban home gardening has gained significant popularity in Bangladesh, driven by the increasing demand for fresh produce and the convenience of growing plants in residential spaces. Efficient watering is pivotal to urban gardening, particularly for indoor plants. This project focuses on the development of a cost-efficient, automated irrigation system designed to address watering challenges, and aims to provide a sustainable and smart solution to improve plant growth and support the growing trend of home gardening in urban areas.

The system utilizes a microcontroller, soil moisture sensors, and water level sensors to monitor and maintain optimal soil moisture levels. A water pump connected to a storage tank is controlled based on real-time data from the sensors, ensuring precise and timely watering. The integration of the Blynk IoT platform enables remote monitoring and control via a smartphone or computer, combining both convenience and accessibility for users.

The system's architecture is designed to be scalable, highly adaptable, energy-efficient, and user-friendly. By incorporating affordable components such as soil moisture sensors and printed circuit boards, the project demonstrates significant cost savings yet is more efficient compared to traditional irrigation systems. The intelligent automation minimizes water wastage, prevents overflow, and ensures consistent hydration for plants, making it an ideal solution for indoor gardening.

This report presents the design, implementation, and evaluation of the proposed system, highlighting its effectiveness in automating irrigation, its cost efficiency, and its potential to enhance urban gardening practices in Bangladesh.

Beyond its application in individual homes, the project opens avenues for commercial use and integration into larger urban agricultural initiatives. Its scalability and modular design make it suitable for indoor plantation and community gardening projects. By addressing the unique challenges of water management in urban environments, the proposed system contributes to sustainable practices and promotes environmentally responsible urban living.
