In this project, the MQ3 and Arduino are used as the Master Control Units to design and construct an alcohol detection system with engine locking for automobiles. The device will continuously check the alcohol detection sensor’s level of concentration and, if it rises above a certain level, will shut off the vehicle’s engine.

Description

DESCRIPTION

This study created a prototype alcohol detection and engine locking system utilizing an Arduino Uno microcontroller connected to an alcohol sensor, an LCD screen, and a DC motor. The MQ-3 alcohol sensor is used by the system to continually monitor alcohol level and identify the presence of alcohol in a driver’s exhale. Our technology can continuously monitor the driver’s breath for alcohol by mounting the sensor on the steering wheel. If the sensors detect alcohol on the driver’s breath, the ignition won’t turn on. If the driver became intoxicated while operating the vehicle, the sensor will still detect alcohol in his breath and shut off the engine to prevent the vehicle from rolling.

Early Project Booking Recommended

Early Project Booking – Strongly Recommended

Students are advised to book their final year or semester project early, even with just a title or brief idea. Early booking helps us reserve your preferred topic, start documentation, diagrams, code planning, and component preparation in advance, and provide timely academic guidance.

You will receive complete documentation (abstract, report, block diagram, circuit, code explanation) well before submission. The working hardware kit will be delivered as per your college schedule. PPTs for reviews, viva, or seminars will be prepared on request.

Book early → Stay stress-free → Focus on learning.
Contact us with just the project title—we’ll handle the rest.
