ARDUINO BASED ALCOHOL SENSE ENGINE LOCK USING GPS & GSM

This project introduces an innovative approach to improving road safety by developing an Arduino-based alcohol detection and engine lock system, integrated with GPS and GSM technologies. The main goal is to prevent driving under the influence of alcohol by disabling the vehicle’s engine upon alcohol detection. The system employs an MQ-3 alcohol sensor to measure the driver’s breath alcohol content. When alcohol is detected, the Arduino microcontroller processes the data from the sensor and activates the engine lock mechanism, thus preventing the vehicle from starting. This functionality is enhanced with GPS technology to provide precise location tracking of the vehicle. In the event of alcohol detection, the system utilizes the GSM module to send alerts to pre-configured contacts, supplying real-time information about the driver’s condition and the vehicle’s location. By incorporating GPS, the system ensures continuous location monitoring, adding an extra layer of security and enabling swift emergency response. The GSM module allows for immediate communication, dispatching SMS alerts to family members or authorities, thereby increasing the safety of both the driver and the public. This comprehensive solution aims to reduce incidents of drunk driving by leveraging Arduino for sensor interfacing and control, and combining it with GPS and GSM technologies for real-time tracking and communication. The proposed system is cost-effective, easy to implement, and scalable, offering a practical tool for enhancing road safety and saving lives.
