Abstract
Alcohol-related accidents are a rising concern globally, with around 2.3 million premature deaths annually attributed to harmful alcohol consumption. This Alcohol Detection System serves as a preventive measure for road safety by integrating with an automobile ignition locking system. Using the MQ3 Alcohol Sensor, it detects alcohol vapor from the driver’s breath and restricts vehicle ignition if alcohol is detected.
Working Principle
The MQ3 Alcohol Sensor detects alcohol molecules in the air and produces a voltage output proportional to the alcohol concentration. This voltage activates a buzzer and LED alert system to notify the user. Additionally, the system can integrate with a vehicle’s ignition to lock operation when intoxication is detected.
Key Features
- MQ3 Alcohol Sensor provides accurate alcohol detection.
- Simple circuitry using IC 7805 ensures a stable 5V DC power supply.
- Adjustable sensitivity through resistor R1 and Pot VR.
- Immediate alerts with buzzer and LED outputs.
Components Included:
- MQ3 Alcohol Sensor – Product Link
- 5V Relay Module – Product Link
- Micro USB Cable – Product Link
- 5V Buzzer – Product Link
