PROJECT NAME-

• IoT besed Alcohol detection to engine locking system.

ABOUT-

• This project Increase road safety and decrease accidents.

Accomplishments.

• I developed an IoT-based Alcohol Detection and Engine Locking System to reduce road accidents caused by drunk driving. Many accidents occur because drivers consume alcohol and still try to drive vehicles. This system focuses on preventing such accidents before they happen.
• The system uses an ESP32 microcontroller as the main control unit. An MQ-3 alcohol sensor detects alcohol from the driver’s breath. When the driver tries to start the vehicle, the sensor checks the alcohol level. If it is within the safe limit, the relay allows the engine to start and a green LED turns ON. If the alcohol level exceeds the limit, the ESP32 turns OFF the relay, locks the engine, and a red LED glows. This prevents drunk driving.
• The system also includes an MPU6050 sensor for accident detection. If sudden vibration or tilt is detected, the GSM module sends an alert message to family members, and the GPS module shares the vehicle’s location for quick help.
• I presented this project in Telangana at a state-level event. At first, I was nervous, but after explaining my project, I felt confident. The judges appreciated my idea and asked technical questions. This experience improved my confidence, communication skills, and interest in IoT technology.

Plan for the week

• We will complete our project and.
