RANCANG BANGUN PENGATUR KECEPATAN KIPAS PEMBUANGAN MENGGUNAKAN SENSOR ASAP AF30 BERBASIS MIKROKONTROLER ATMEGA8535

Abstract

Have been made by design to develop build Regulator of speed fan dismissal use censor of smoke of AF30 base on Mikrokontroler ATMEGA8535. Design to develop build this can be exploited to assist to arrange draught in smocking of room/smoking area. System made consisted of the network sensor smoke (AF30) therewith buffer, system of minimum of mikrokontroler ATMEGA8535, network of driver of transistor and display in the form of LCD. This System put hand to moment sensor AF30 detect smoke of cigarette deputizing gas of hydrogen and etanol on the air. To can be processed by mikrokontroler hence tension of output from censor in the form of the analogous sinyal have to be altered into digital form use Internal ADC0 of ATMEGA8535. After data change in the form of digital hence output from network of the ADC can be attributed by network of mikrokontroler functioning as input beet. Output from this mikrokontroler in the form of pulsa from setting Pulse Width Modulator (PWM) of Wafting from mikrokontroler ATMEGA8535. Assess change of smoke accepted by censor and speed turn around visible fan at appearance LCD. The system have succeeded realized and can assist as regulator of draught at a column of (smoking room/smoking area).
