In this video, I have explained how to make an **Alcohol Detector Project using Arduino and MQ-3 Alcohol Sensor**.
This project is very useful for detecting alcohol presence and can be used in **vehicles, offices, industries, and safety systems**.
The MQ-3 sensor detects alcohol vapors from breath and sends the signal to Arduino. When alcohol is detected beyond a certain level, the buzzer and LED get activated to give an alert.
This project is ideal for **school science exhibitions, college mini projects, and beginners in Arduino & IoT**.
🔧 *Components Used:*
Arduino Uno
MQ-3 Alcohol Sensor
Buzzer
LED
Connecting Wires
Breadboard
📚 *Topics Covered in This Video:*
Working principle of alcohol detector
Circuit connections
Arduino code explanation
Real-time demonstration
