This project presents a design and development of an automated plant watering unit that assists in maintaining optimal plant hydration through real-time soil moisture monitoring. The system employs soil moisture sensors to continuously assess moisture levels and automatically activates watering when the soil moisture drops below a specified threshold. This will ensure efficient water use, promote healthy plant growth and same time conserve water resources. The unit is designed and developed as a low-cost and user-friendly solution, the unit is suitable for various applications, including home gardens, community green spaces, and agricultural settings. Its adaptability and focus on resource efficiency make it an effective tool for enhancing plant care and supporting sustainable watering practices.
