Smart Evacuation Alert System using IoT

Fire protection is critical. In both residences and industries, a system for protecting people from leaking gas and fire is critical. The majority of existing fire safety systems is an effort by signalling with an alarm or words. This does not draw the attention of people who are not present at the scene of the incident. As a result, a smart evacuation alert system capable of overcoming this limitation is required. The proposed work performs multiple tasks which are detecting the flames, controlling the temperature, detecting the smoke or gas. The proposed work deals with a flame sensor that detects flame in the room show the signal through the relay, the MQ-2 gas sensor it detects the smoke in the room shows the signal through the relay, LM-35 temperature sensor it continuously monitors the temperature of the room by indicating through the relay. Every sensor has an individual bulb so if there is any problem, the bulb will automatically switch on with the help of a relay and immediately and the problem can be rectified which occurred respectively in the room. Arduino Board is used as the control circuit in this project. Relay acts as a switch for each sensor. Every sensor has its own respective function. Using the Arduino Board and all the sensors the work is completed and tested successfully. This is based on interfacing each sensor to the Arduino and making it useful to the society.
