Automated Fire Suppression System

Abstract

This study demonstrates the design, development, and performance evaluation of an Automated Fire Suppression System that uses the Arduino Uno R3 as its primary micro controller. The proposed system is intended to enable an autonomous, real-time response to fire occurrences by combining infrared-based flame detection, closed-loop control logic, and electromechanical actuators. By continuously monitoring the environment for infrared radiation emitted by flames, the system can detect the presence of a fire, determine its relative location, and initiate a targeted suppression mechanism without human participation.
The system contains a flame sensor module for fire detection, dual-axis servo motors for directional alignment, and an active fire suppression water pump handled by a relay. A structured input-process-output (IPO) model and closed-loop control architecture were used to enable accurate detection, precise nozzle positioning, and adaptive responses based on real-time feedback. Detection accuracy, mechanical reliability, and response consistency have been tested by experimental testing under various fire conditions. The results show a 100% response rate for fire detection and suppression throughout the effective operating range of 30 cm to 80 cm, proving that the system has the capability to neutralize medium to large fire sources effectively.
