Purwarupa Sistem Pemantau dan Peringatan Kadar Gas Karbon Monoksida (CO) pada Kabin Mobil Berbasis Mikrokontroler ATMega8
Abstract: High growth in
vehicle, contribute air pollution and reduce human health quality. One of
pollutants that generated by motor vehicle emissions is carbon monoxide (CO).
CO gas can cause health problems for humans, even if exposed to long periods
time will cause death. Emission test devices have been widely available in many
auto repair shops, but at the moment emission testing, only read gas source or
emissions sources from the muffler hole. Cabin space usually escaped from
checking, whether there is pollution that enters the cabin or not. This final
project has a purpose to design a carbon monoxide detector devices which will
show the levels of carbon monoxide (CO) into 4 categories of air quality,that
are safe, wary, watch out, and danger. System will automatically warning the
driver if the gas exceeds the threshold. Microcontroller that used as the
central data processing data is microcontroller Atmega 8, by ATMEL and use gas
censor TGS 2442. Design begin with a hardware schematic and software design
using BASCOM-AVR. Implementation phase include the implementation of the
physical device, programs, and censor. Testing phase is done by testing the
tool using 3 gas source, that are cigarette smoke, motorcycle exhaust, and car
exhaust. The test result showed that the highest error rate on these tool when
compared with a comparable gas analyzer scott instruments is 6.46%, with 93.54%
accuracy rate. This CO gas monitor hasadvantage easily portable and include
three actuators, that are LCD will show the levels of CO gas, buzzer will give
warning sound when gas exceeds the threshold, and the vibrating motor provide
tactile warning to the user.
