  This system will detect alcohol by using the alcohol sensor.The analog output of this sensor is now provided to the microcontroller for further processing. Depending on the input, microcontroller calculates the percentage of alcohol and displays it on an LCD display. It also sounds an alarm, if the amount of alcohol exceeds a particular amount.
