IOT BASED VEHICLE OVER SPEED INDICATION AND VEHICLE TRACKING & ALCOHOL DETECTOR WITH ENGINE LOCKING USING GSM, GPS

Abstract

Drunk driving is one of the major reasons behind road accidents worldwide. In all of the road
accident cases worldwide drivers have been observed to have excess alcohol content in their
blood. So we here design a smart alcohol detector system using arduino coupled with gsm
and gps for location transmission. The system allows for automatic sensing of alcohol in
breath, we also use a motor to demonstrate as a vehicle. We further use a GPS module with
GSM to send an SMS message to the concerned person in case alcohol is detected and stop
the vehicle motor. The system consists of an Arduino Uno board along with an Mq-3 alcohol
sensor for detection and a GSM/GPS Module for notification. In the case of a sober driver i.e.
the alcohol is under the permissible limits the car will normally which is indicated by the
motor rotating, but in the case of a drunk driver, the alcohol content would be higher than the
permissible limit which is detected by the alcohol sensor and the Arduino controller which
stops the motor so that drunk driving can be avoided and also sends an SMS notification to
the authorities or family members along with the location of the car so that assistance can be
provided. The project also has an LCD for parameter display.
