In order to promote sustainable agriculture, this project intends to create a rainwater harvesting system. This research focuses on the use of rainwater as an efficient alternative source in light of the growing awareness of the significance of managing water resources, particularly in the agricultural sector, which frequently faces the challenge of water scarcity. This encourages the more sustainable and responsible use of natural resources while also lessening reliance on traditional water sources. The proposed system is designed to detect soil moisture and activate automatic irrigation when needed by the plants. The ESP32 microcontroller technology will be used to manage this system, ensuring efficient and effective use of rainwater. By automating the irrigation process based on soil moisture data, this system can ensure that plants receive the right amount of water at the right time, avoiding waste and improving crop yields. By introducing this innovative solution, the project is expected to make a significant contribution in addressing the issue of water scarcity in the field of agriculture. The comparison between the Automated Rainwater Harvesting System for Plant Irrigation project and previous studies using rainwater harvesting technology in the context of agriculture shows different approaches in managing water resources for plant irrigation. In this study, key elements such as component selection, control systems, and technology application are used in each system to ensure the effectiveness and efficiency of rainwater usage. The findings obtained from various literature studies provide perspectives on the advantages and challenges in the application of rainwater harvesting technology, as well as how these systems contribute to sustainable agricultural practices and the reduction of water resource wastage. This comparison aims to examine whether the developed project provides a better solution or supports improvements to existing technology. The aim of this project is to create an effective autonomous rainwater collection system in order to solve the problem of agricultural water scarcity. The system’s goal is to catch surface-level rainfall and hold it in a collection tank for use in irrigation. The entire operation is controlled by an ESP32 microcontroller, and the water level in the tank is tracked by a water level sensor. The water level falls below a certain threshold, which triggers the water pump to move water into the collection tank. The system’s many parts work together to guarantee steady water flow, enabling the effective use of the rainwater gathered for farming purposes. The system’s ability to effectively collect and store rainfall increases the amount of water available for plant irrigation, according to the study’s findings. The electrical circuits and component interactions can be optimized to provide more stable and long-lasting performance, even while the system functions well as is. The system’s dependability can also be increased by making it more resilient to harsh weather events like intense rain or high temperatures. Overall, by offering an automated solution for improved water management, lowering water waste, and guaranteeing a more reliable water supply for plants, this initiative significantly benefits the agricultural industry. The suggested enhancements could further increase the system’s effectiveness and relevance in tackling upcoming water scarcity issues.
