Main Idea

My project idea aims to save life and reduce the impacts of fire disaster.  My solution is based of using autonomous system that can detect the fire and accordingly it  raise alarms through lamps and buzzers.

But not only alarms but also taking other actions like opening doors locks to ease evacuation process and  to operate suction fans to reduce the impacts of the smoke.

Also to give additional feature of manual testing the functionality of the system by manual switch.

Project Components

-Arduino UNO ; to perform programming logic and to make automated system

-Flame sensor; to detect fire occurrence

- On/Off switch; to manual check system functionality

-Bulb with relay; to produce light alarm

-Buzzer; to produce sound alarm

- 9V Adaptor; to supply circuit with the power

Main Operation sequence

1- When there is a fire , the digital flame sensor will operate and  activate its alarm signal.
The Arduino code will be written so that when "digital input" corresponding to the flame detector is activated , it will set a variable of "Fire is detected"

2- When the button is pushed ,  the Arduino code will be written so that when "digital input" corresponding to the push button  is activated , it will set a variable of "Manual activation is detected"

3-  When (Fire is detected  OR Manual  activation is detected ) :
-  Light alarm will be activated
-  Buzzer alarm will be activated
