Design and implementation of Sonic based fire extinguisher system

Electronics and communication engineering

It is known that the technological advancements are increasing at a faster pace. But the utilization of technologies in various sectors are very low. People have witnessed various accidents caused by fire. The Common system consists of a water based automated fire extinguisher system. This might cause water shortage if the water level is very low. This cannot reduce the fire in critical situations. The system is only partly efficient.So we propose a system where we can efficiently control the fire using Sound based Fire extinguisher. The sound waves are utilized to reduce the fire by performing various processes.The proposed system overcomes the drawback in the existing system. The system here consists of a Frequency generator. The frequency generator is used to generate a signal of particular frequency. Based on the user input a particular frequency is provided to the PWM driver. The PWM driver is controlled by the Arduino controller. Now the PWM driver provides the frequency to the amplifier circuit. The amplifier amplifies the frequency and provides the output to the FET transistor. The output generated is efficient to clear the fire present in an area. If fire occurs in office it will be detected using temperature sensor and sonic fire extinguisher will be activated. Using camera located in that place also the fire will be detected and fire extinguisher will be activated.
