Vehicle Accident Prevention System Embedded with Alcohol Detector
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
the main aim of this project is to develop a system that can detect the alcohol content in the air exhaled by the driver and automatically turn off the car if alcohol percentage exceeds the limit. In this project we are using 8051 family (89s52) micro controller. the alcohol sensor used in this project is mq-3 which to detect the present of alcohol content in human breath. alcohol sensor gives out analog data that can’t be analyzed by 8051 microcontrollers. The data received from alcohol sensor is converted into digital form with the help of digital converter (analog to digital converter). after that the data is stored in microcontroller and then compared to the threshold values. if the value is beyond its set limits, then with the help of program controller takes appropriate action which controls the ignition system. here we used electro mechanical relays to control the ignition system. in this project by controlling the ignition system, we can prevent accidents that occur due to drink and drive.
