Change and progress are taking place right now. The world is turning more and more toward technology. The safety of new construction is a problem in the modern day. As the population grows, more and more structures are needed. Accidental fires occur in various types of structures for a number of reasons. If we look at the past several decades, we have seen a number of fatalities brought on by building fires. Every year, our nation suffers financial losses as a result of fire catastrophes. The biggest worry right now is how to prevent these fire incidents in buildings with high ceilings. Traditional fire detection methods are unable to stop such mishaps. Additionally, they are unable to alert owners about fire incidents. Additionally, they are unable to alert owners about fire incidents. IOT has a significant role to play in this. Internet of things, or IOT. These fire mishaps can be completely prevented or controlled by IOT. IoT holds one of the leading positions in technological growth across the globe. Following computers, the Internet, and mobile communications, it is another sector of the information economy. Firefighting, fire monitoring, and safety management systems are crucial uses for Internet of Things technology. It talks about the IoT system framework for planning, monitoring, and battling fires. Building fire accidents can be controlled using an IOT-based fire detection system. An IOT-based system can offer the finest security for tall buildings. The owner, user, alarm, etc. will receive a message alerting them of the fire from an IOT-based fire detection system that can detect temperature, smoke, short circuit, and other factors. In order to take safety precautions, it can also send an alarm message to the local fire department and police system. Multiple sensors, a communication system (Bluetooth, GSM, NodeMCU), motion planning (manual patrolling), and an Android application for manual system patrolling make up the Fire Detection System. For safety reasons, this fire detection system can be employed in academic institutions, workplaces, and businesses. In-depth discussions of the IOT, IOT-based fire detection systems, and IOT applications that can be used to improve building fire safety are covered in this article. Additionally, it covers how IoT and wireless sensor network technology might be applied to meet firefighting needs
