Abstract—The main objective of this paper is to develop a distance measurement system for a smoke detector circuit to measure the distance of fire. This ultrasonic distance measurement system will calculate the time of flights (TOF) of the reflected echoes from the smoke particle of fire. The reflected echoes are cross-correlated with the transmitted pulses to find the distance. The measured distance should be given to smoke detector by the sensor signal processing and then the fire sprinkler system can be activated through this triggering signal. The fire sprinkler system will spray required amount of water only in that particular fire originating place according to the measured distance. This proposed system is designed to reduce the extent of fire-spreading in an efficient way so that it can protect the properties and lives from further fire hazards.
