Alcohol breath Analyzer using PIC microcontroller with display

Alcohol breath Analyzer using PIC microcontroller with display

PROJECT TYPE

Microcontroller(PIC16F877A) hardware design with software development (Device Driver). PIC micro controller (PIC16F877A) based.

 PROJECT DESCRIPTION


                                           
                               Our main motivation for creating the alcohol breath analyzer is to get alert from drunken people. In general, in intoxicated people are usually more care less and destructive than those not under the influence in our particular house, kitchen and library are 2 rooms that are vocationally left by an intoxicated. We decided to fabricate device that would allow sober housemates to use the facility while keeping the drunken ones out. Our breath analyzer initiates an alarm when a threshold concentration of alcohol is reached. The microcontroller does the above job it receives the signals from the sensors, and this signals operated under the control of software which is stored in ROM.
