IoT-based Fire Alarm System. These devices must also be connected to a computer for data handling and transmission. Using the Twilio app, which will communicate the message to the system, makes it possible to accomplish more. As a result, the hardware and software components that make up the Fire Alarm System's fundamental building blocks are both present. This makes it easier for us to spot and put out fires immediately.

Prior to a fire consuming their houses, people need to be warned, and fire alarm systems are crucial for this. But in today's world, installing fire alarm systems takes a lot of wiring and labour. Users become less inclined to put them in their residences as a result. As a result, we are suggesting a wireless, simple-to-install fire alarm system that is based on the Internet of Things. The suggested system is an ad hoc network that is dispersed throughout the home. This system uses an infrared flame sensor and a microcontroller (ESP8266 node MCU), which continuously senses the environment to look for fire. The microcontrollers establish their own Wi-Fi network. When a sensor detects a fire, the sensor sends a signal to a microcontroller, which activates a local alarm, an SMS to the user, and a call to the user. Sending an SMS to the system allows the user to inquire about the status of his home. A prototype of the suggested system was created, and it successfully implemented the intended functionalities with an average latency of less than 30 seconds.

1.2 LITERATURE REVIEW In [1], the research on fire using fire alarm systems is discussed. In [3], Fire Behaviour and Fire line Safety is discussed. In [5], Review on Forest Fire Detection using sensors is discussed. In [7], Forest Fire Smoke Video Detection Using Spatiotemporal and Dynamic Texture is discussed. In [10], Multilayer Neural Network Based Fall Alert System Using IOT is discussed. In this paper, we introduce Node MCU instead of Arduino. It will consume less power from the source.

Key words: Node Mcu, Buzzer, LED,IOT Cloud.

1.3 INTERNET OF THINGS

INTRODUCTION:

The term "Internet of Things" (IoT) refers to a scenario in which objects (including people, animals, and machines) are given unique identifiers and the capability to automatically transmit data over a network without requiring human-to-computer interaction. ESP8266 Node MCU is an open source IoT platform that includes firmware that runs on the low cost Wi-Fi enabled ESP8266 Wi-Fi SoC from Espressif Systems and hardware that is based on the ESP-12 module. In this IoT Fire Alarm, we are using two GPIO pin to get the digital data from the flame sensor. ESP8266 Node MCU is a key component of the Internet of Things.

1.1 PREAMBLE The two fire alarm boxes that came with the classic fire alarm system each had a telegraphic key. When someone saw a fire, they would turn the handle on the fire alarm box, which would then broadcast the fire alarm box number and the specifics of the incident to a central alarm station. The fire department reaction team would be informed of the box's position as soon as the station's telegrapher received the message. Since we are in the twenty-first century, everything has been updated. These outdated techniques won't allow us to save everything. We are launching the IoT-based fire alarm security system for this reason. Our time and lives may be saved by this. One of the most dangerous fire tragedies has a solution: the fire alarm system. ESP8266 Node MCU, Flame sensor, and Buzzer are only a few of the hardware
