Abstract

The need for fire extinguishing methods is essential as fire accidents are disastrous in nature, leading to unrecoverable loss. The current fire extinguishing technique comes with various drawbacks. The existing techniques are not eco-friendly. The need for brand spanking new hearth conclusion techniques is important as hearth accidents cause deaths and injuries. Sound waves may well be one in every of the potential alternatives as hearth extinguishers. The low frequency acoustic waves spilled from a speaker tend to extinguish the flames. Our aim is to develop a portable fire extinguisher robot using a microcontroller and to analyse the effect of different frequencies of sound waves on flames. Experiments need to conduct for suitable sound wave frequency range to extinguish flame and to analyse the acoustic -flame interaction through observations using a portable and innovative approach to reduce the overall cost. Microcontroller and Mobile sensors are used to record the data and control the robot . Wireless transceivers(LoRA) are used to control the fire extinguisher robot remotely.

Key words: Sound waves, fire extinguisher, mobile sensor, Wireless transceiver (LoRa).
