DIY FIRE EXTINGUISHER DRONE USING IoT

Abstract: Fire accidents pose a serious threat to human life, property, and the environment, especially in industrial areas, forests, warehouses, and residential buildings. Traditional firefighting methods often expose firefighters to hazardous conditions and may result in delayed emergency response. This paper presents the design and development of a DIY Fire Extinguisher Drone, a low-cost unmanned aerial vehicle (UAV) designed to detect and suppress small-scale fires efficiently. The proposed system integrates an ESP32 microcontroller, flame sensor, smoke sensor, GPS module, camera module, relay-controlled water pump, and brushless DC motors to create an intelligent firefighting platform. Upon detecting fire, the drone identifies the affected area, activates the onboard extinguishing mechanism, and simultaneously transmits real-time video and GPS coordinates to the operator for effective monitoring and emergency response. The lightweight design, affordable hardware, and modular architecture make the system suitable for educational institutions, industries, and disaster management applications. Experimental evaluation demonstrates reliable fire detection, rapid response time, and effective suppression of controlled fire scenarios while reducing human involvement in dangerous environments.
The proposed DIY Fire Extinguisher Drone provides an economical, efficient, and scalable solution for enhancing firefighting operations and improving public safety through modern UAV technology.
