ABSTRACT This final assignment makes an application smoke detector with alarm that is controlled by microcontroller AT89S51 based on the concentration of the smoke detected by smoke censor AF30. This final assignment uses an observation method and a book literature study to collect data in the preparation of this final assignment. This application of smoke detector examines to test the each module used in all network. The examination result was concluded by giving some input at smoke censor AF30 that comes from of cigarette smoke. AT89S51 microcontroller than processes the signal and triggeles a buzzer to produce sound. It was concluded that : 1. At the time of smoke with its concentration is more than 10ppm detected, buzzer would sound and yellow led indicator turned on. 2. At the time of smoke with its concentration is equal to 100ppm detected, buzzer would sound more quickly and red and yellow led indicator turned on.
