AUTOMATED BREATH ANALYZER FOR ETHANOL DETECTION AND MONITORING

This project aims to develop a system for detecting alcohol levels in a vehicle driver's breath using an MQ-3alcohol sensor interfaced with an ESP8266 NODEMCU microcontroller. The system's primary function is toprevent the ignition from starting if alcohol is detected above a certain threshold, thereby enhancing road safety.Concurrently, it ensures continuous power supply to critical systems like power steering and braking through a 4-channel relay module, regardless of the alcohol detection status. This dual-functionality design seeks to mitigatethe risks associated with drunk driving by integrating real-time sensing and control mechanisms into the vehicle'soperational frameworkThe ESP8266 NodeMCU establishes a Wi-Fi connection to host a webpage, displaying real-time alcohol levelreadings. Users can access this webpage via the ESP8266's IP address, facilitating monitoring and management.This integration enhances vehicle safety by combining alcohol detection with continuous system operation andaccessibility through a web interface.
