Pengesan alkohol atau lebih dikenali sebagai ‘breathalyzer’ memainkan peranan penting dalam memantau kepekatan alkohol dalam aliran darah seseorang. Projek ini adalah merekebentuk dan membangunkan ‘breathalyzer’ yang disambungkan ke suis pencucuhan (ignition) Modul perkakasan adalah termasuk mikrokontroler PIC16F877A, sensor alkohol, panel LCD dan litar suis pencucuhan. Komponen perisian adalah pengaturcaraan dan kod yang di programkan ke pengawal mikro PIC. Apabila diaktifkan, sistem ini mampu mengesan kepekatan alkohol didalam sampel nafas seseorang dan memaparkan jumlah yang dikesan dalam peratusan BAC (Blood Alcohol Concentration) pada panel LCD. Kemudian, dalam linkungan yang telah ditetapkan, sistem akan membuat pilihan samada menghidupkan atau mematikan litar suis pencucuhan. Kata kunci: Pengesan alcohol; kepekatan alkohol dalam darah; pencucuhan; alcohol; mabuk A breath alcohol detector or better known as a breathalyzer plays a vital role in monitoring alcohol concentration in a person’s bloodstream. This project involves the design and development of a breathalyzer device which controls an ignition switch. The hardware modules include the PIC16F877A microcontroller, alcohol sensor, LCD panel and ignition switch circuitry. The software component includes the programming and source code which is implemented via the PIC microcontroller. Upon assembly, the system is able to detect the alcohol concentration in a person’s breath sample and displays the detected amount in terms of BAC (Blood Alcohol Concentration) percentage on the LCD panel. According to the amount, the system decides whether to enable or disable the ignition switch circuitry. Key words: Breathalyzer; blood alcohol concentration; ignition; alcohol; drunkDownloads
