My project is about the safety for people in skyscrapers if there is a fire in the building so the people could be alerted by the piezo and the sprinkler placed in every floor will be turned on to extinguish and the exhaust which also placed at every floor will be turned on to take the out the smoke as well. As we know that if there is smoke in the skyscraper so the visibility is zero so that's why I have placed a neopixel strip at the exit gate to show the way out and I have used green color for my neopixel LED strip because when there is smoke in the room, green color can effectively be seen and also I have a bulb which will indicate us.I decided to make it because in tall buildings like Burj Khalifa its hard to know where is the fire so the gas sensor will help us in the fire by telling us there is fire somewhere so people could exit quickly and the fire department could quickly come to put off the fire till it spreads the whole building.

My project works like when the fire will reach the gas sensor the piezo will buzz and red light will glow and the bulb will also glow they will indicate everyone in the building that there is fire in the building the exhaust motor and the sprinkler motor will be turned on to extinguish the fire and the exhaust motor will be turned on to take the smoke out of the building. The green neopixel LED strip placed at gate will be turned on to show the way to exit this is how my project works.

EXPANDED TECHNICAL DETAILS

Life-Safety Automation Hub

This project is a high-reliability security system designed to detect and react to fire hazards in commercial or residential structures.

• Early-Warning Sensor Suite: Integrates an MQ-2 Smoke/Gas sensor and a KY-026 Flame sensor. The Arduino constantly polls these sensors and triggers an alarm if thresholds are exceeded.
• Automated Mitigation: Upon detection, the Arduino pulls a HIGH signal to a dedicated Relay. This automatically activates a motorized ventilation fan and a water-pump-based sprinkler system simultaneously.

Remote Visualization

• Tinkercad Circuits Simulation: Includes a detailed simulation model for testing the logic safety-loops and timing before physical installation, ensuring the code is fail-safe.
