Helmet for Alcohol Detection

Abstract

This project will include whether the two wheeler driver has drunken alcohol or not. If driver is drunk then the helmet will indicate red signal and if you insert the key the ignition key will not function. Conveniently if it indicates yellow signal. The driver can start the bike and go for a drive. The project will project the two wheeler drivers to drive safety without drinking alcohol. This project is fully equipped by 435MHZ transmitter the receiver alcohol detector red indicator, yellow indicator, relay control circuit and helmet. It is a genuine project for two wheeler drivers to drive safety. Alcohol sensor is fixed for detecting alcohol content from the breath. So it can be placed just bellow the face. It detects the alcohol content from the breath. So the wearing of helmet is confirmed by cur system and similarly alcohol sensor fitted in the mouth piece of the helmet detects the alcohol within the breath and sends the amount of alcohol to the controller. If both of the criteria’s are met in an appropriate manner then the two control signals are sent from the helmet unit to the vehicle control unit. The decoded RF signal is distributed to the controller within the vehicle unit two to start out/stop the vehicle. If the control signals from alcohol sensor is detected then the vehicle can begin, otherwise the vehicle won’t begin.
