Abstract

Fire accidents pose serious threats to life and property, especially in confined or inaccessible areas. This project presents a Smart Firefighting Robot Car that integrates IoT, automation, and user-controlled features. Built on an ESP32 microcontroller, the system uses IR flame sensors for fire detection and a servo motor-based water spraying mechanism for extinguishing. It offers two modes of operation: Auto Mode, where the robot navigates toward the fire and suppresses it automatically, and Manual Mode, where the user can control it remotely using a Bluetooth-enabled custom mobile app. An OLED display shows live system status, while ThingSpeak cloud is used for storing detection data and generating alerts. Equipped with a buzzer and LED indicators for warnings, the system is designed for real-time, safe, and effective firefighting. Its applications span homes, factories, warehouses, and laboratories.

Project Information

The Smart Firefighting Robot uses an ESP32 as the brain of the system. The fire is detected using an IR flame sensor, while a motor driver controls the DC motors to move the robot in the direction of the fire. A servo motor operates a mini water pump/nozzle to spray water. The robot features dual control modes: autonomous (sensor-driven) and manual (via BLE custom mobile app). An OLED display shows current mode, sensor readings, and status messages. The system uploads fire detection data to ThingSpeak Cloud for monitoring, logging, and visualization. A buzzer and LEDs act as alert indicators, enhancing safety. This integration of hardware, IoT, and mobile control makes the robot a reliable solution for rapid fire suppression in hazardous or hard-to-reach environments.

Project Objective

The objective of this project is to develop a low-cost, IoT-enabled firefighting robot that can detect fire, extinguish it, and provide real-time monitoring via a custom mobile application. The robot will operate in two modes: Auto Mode, where it autonomously detects fire using flame/IR sensors and sprays water through a servo-controlled nozzle, and Manual Mode, where the user can control it via Bluetooth through a custom mobile app. An OLED display will show system status, while ThingSpeak cloud integration will store real-time fire detection data for monitoring and analysis. The design aims to provide an effective, safe, and flexible firefighting solution for indoor and outdoor scenarios where human intervention might be risky.
