This document describes the design of a fire detection and extinguishing system using IoT technology. The system uses flame, smoke, and temperature sensors to detect fires and activates a water pump and sprinklers to extinguish the fire. It is intended to automatically detect and put out small fires without human intervention in order to reduce risks to firefighters. The system would detect fires, locate the fire source, and use an on-board water pump and sprinklers to extinguish the fire from a safe, remote distance.
