ABSTRACT


An alcohol detector: - is a electronic device that detect alcohol in the breath of a person that has consumed the liquire. In this project, the design involved the hardware module and software module. The hardware module consist of sensor circuit (MQ – 3), the pic (Microcontroller circuit), the L.C.D. Circuit and the alarm circuit. The software module include, the programming on plc microcontroller that sends the information to the encoder using C – programming, the sensor detects the alcohol  and then signal to the micro controller and display the result on the L.C.D upon the assembly. Then the buzzer alarm will start ringing, the alcohol detector is able to detect alcohol in the breath of the person.

CHAPTER ONE


1.0       INTRODUCTION


This report presents the progress in using a alcohol detector, a device that senses a change in the alcoholic gas content of the surrounding air. The sensor will then analyse the amount of alcoholic vapors and offer the user some indication of the amount of alcohol present. Nowadays alcohol sensor plays a significant role in our society and it has vast application. This project detect the content of alcohol in the breath and thus it attempt to clap down alcoholic. This project use PIC16F877A, LCD display, MQ-3 alcohol sensor and buzzer. The output of the sensor is directly proportional to the content of alcohol consumed. We try to develop this project to make it available for everyone. This project won’t cost much, but it will bring much for it concentrate to humans safety. This project has a preventative effect which can stop accident from the beginning. In this project, initially we check whether the person id drunk or not by using the MQ-3 alcohol sensor. In this project sensor circuit is used to determine if a person has consumed alcohol or not. To this end, we have designed such a system that when alcohol is detect alarm is raised.


1.2       AIMS AND OBJECTIVES


The aims of this report is to design and construct an alcohol detector that sound alarm with the aid of buzzer.


-           To design the power supply circuit


-           To design and construct an alcohol detector which will detect alcohol in the breath through the MQ-3 sensor and pass the information to the micro controller and display the output through the L.C.D (Ayala, 8051).


1.3       SCOPE OF THE PROJECT


The Scope of study is to detects the content of alcohol in the breath and thus it attempts to clamp down alcoholics. This project include the following criteria: -


i.          The study and application of MQ-3 sensor


ii.         Architecture of PIC16F877A


iii.        The PIC micro controller using C language programming


iv.        The LCD display the buzzer alarm


v.         The knowledge of soldering and soldering of electronics.


1.4       JUSTIFICATION AND SIGNIFICANT OF THE PROJECT


By completing this project: -
