Abstract: We design the fire detection system using four flame sensors in the Fire Sensing and Extinguishing Robot, and program for fire detection and extinguishing procedure using sensor based method. The fire fighting robot is equipped with four thermistors / flame sensors that continuously monitor the temperature. If the temperature increases beyond the predetermined threshold value, buzzer sounds to intimate the occurrence of fire accident A warning message will be sent to the respective personnel in the industry and to nearby fire station with the GSM module provided to it. Fire Sensing and Extinguishing Robot continuously monitors the temperature at four sensors and if fire accident is true, the robot moves to the direction to which the temperature is recorded to be the relatively maximum among the four sensors and extinguishes the fire with water pump provided to it. After extinguishing the fire Robot comes back to its initial position.
