In this project, we are going to describe the usage and numerous advantages of a Fire alarm system in daily life. It has a great scope in daily life as it can be used in various fields and the best part about it is, we will receive a text message if the fire is detected. This project can be implemented in industries mines, colleges, etc. Security and automation are prime worries in our everyday life. The way to deal with home and industrial automation and security framework design is nearly institutionalized these days. Everybody wants to be secured. So, every user can use this fire sensor, temperature sensor, gas sensor, the smoke sensor at home and enterprises.
