Smart Fire Detection and Response System
This paper presents the design and development of an IoT-based smart fire detection and autonomous fire-fighting robot using the ESP32 microcontroller. The system aims to reduce human risk in hazardous environments by enabling early fire detection and automatic suppression. It integrates multiple sensors, including flame sensors, a temperature sensor, and an ultrasonic sensor, to accurately detect fire and navigate obstacles. The ESP32 processes real-time data and controls the robot’s movement through a motor driver while activating a water pump via a relay module to extinguish fire. A servo motor ensures directional water spraying for effective suppression. Additionally, IoT connectivity allows remote monitoring and manual control through a mobile application. Experimental results demonstrate reliable performance, fast response, and improved safety, making the system suitable for residential and industrial applications.
