Smart Vehicle Safety System with Smoke Detection

Smart Vehicle Safety System with Smoke Detection

Description:

The Smart Vehicle Safety System with Smoke Detection is a 40 × 50 cm student working model that demonstrates a modern vehicle safety mechanism. Built using foam board or sun board, this model uses an Arduino UNO microcontroller and a smoke sensor to monitor the vehicle cabin or engine compartment for early signs of smoke or fire.

When smoke is detected, the system triggers multiple safety responses:

• An alert message appears on the 16×2 LCD screen with I2C module.
• A buzzer sounds an alarm.
• LEDs start blinking as visual indicators.
• Vehicle motion (simulated using BO wheels and DVD motors) may stop.
• A servo motor can simulate emergency actions (like unlocking a door or vent).
• A push button allows reset or manual override.

This interactive, automated model is perfect for school science exhibitions and showcases the integration of embedded electronics and real-world safety applications.

🧰 Materials Used:

• Foam board / Sun board – base platform (40 × 50 cm)
• Arduino UNO Microcontroller – system brain
• 16×2 LCD Screen with I2C Module – display warning messages
• Smoke Sensor – detects smoke presence
• Power Distribution Board – supplies power to modules
• Jumper Wires – for connections
• BO Wheels & DVD Motors – simulate vehicle motion
• Servo Motors – simulate door control or fire response
• Buzzer – sound alert
• Push Button – reset/manual control
• LEDs – visual smoke alert

⚙️ How It Works (Working Principle):

1. The smoke sensor continuously checks for smoke in the environment.
2. If smoke is detected:
   • LCD shows a warning message.
   • Buzzer sounds.
   • LEDs flash.
   • Motors simulate vehicle stopping.
   • Servo performs a safety action (optional).
3. A push button can reset the system once safe.

✅ Features:

• Real-time smoke detection and response
• Uses LCD, buzzer, and LEDs for multi-level alerts
• Simulates vehicle halt during emergency
• Controlled by Arduino UNO for accurate processing
• Ideal for road safety and fire hazard awareness demos

🎯 Educational Value:

Students learn about:

• Arduino programming and automation
• Sensor integration with microcontrollers
• Real-world safety systems in vehicles
• Use of servo, LCD, motors, and power management
• Design and logic of emergency response systems
