This project focuses on developing a smart fire suppression robot integrated with a rainwater harvesting system to improve safety while making better use of available water. The system automatically collects rainwater during rainfall and stores it in a tank, while continuously monitoring the water level for effective usage. The robot is equipped with flame sensors to detect fire and can respond either autonomously or through Bluetooth control. A compact water pump draws water from the tank and sprays it through a movable nozzle, allowing accurate and effective fire suppression. The design is simple, portable, and easy to use, making it suitable for real-world applications. It reduces the need for constant human involvement and helps ensure a quick response during emergencies. In addition, the system is built using low-cost and easily available components, making it affordable and practical for wider use. By combining rainwater collection with automated fire response, the project provides a reliable and efficient solution that supports both safety and better use of natural resources.
