Abstract
Pencemaran udara adalah suatu kondisi di mana kualitas udara menjadi rusak dan terkontaminasi oleh zat-zat, baik yang tidak berbahaya maupun yang membahayakan kesehatan tubuh manusia dan dengan adanya karbon dioksida (CO2) yang berlebih di udara dapat mengurangi kesegaran da kebersihan udara yang kita hirup. Karbon dioksida (CO2) juga bias menjadi polusi udara apabila kadarnya dalam udara berlebih, dapat mengakibatkan gangguan pernapasan juga keracunan terhadap susunan saraf. Bahkan dalam kadar tertentu akan membunuh makhluk hidup yang ada di bumi. Oleh sebab itu diperlukannya alat monitoring emisi gas karbon dioksida (CO2) berbasis mikrokontroler. Mikrokontroler STM32F4 Discovery digunakan untuk memproses sinyal keluaran dari modul sensor karbon dioksida MG 811. Berdasarkan analisa data, dapat diketahui faktor cakupan sebesar 1.826 diperoleh dari T Student dengan tingkat kepercayaan 95% dan alat ukur memiliki nilai ketidakpastian diperluas (Uexp) sebesar ± 7,502121 dengan tingkat kepercayaan 95% sehingga diperoleh hasil pengukuran x = (522,3 ± 7,502121)ppm. =================================================================
Air pollution is a condition in which air quality becomes damaged and contaminated by substances, both harmless and harmful to the health of the human body and the presence of excess carbon dioxide (CO2) in the air can reduce the freshness and cleanliness of the air we breathe. Carbon dioxide (CO2) is also biased into air pollution when the levels are in excess air, can cause respiratory distress also toxicity to the nervous system. Even in a certain degree will kill the living creatures that exist on earth. Therefore the need for monitoring tool emission of carbon dioxide gas (CO2) based on microcontroller. The STM32F4 Discovery Microcontroller is used to process the output signal from the MG 811 carbon dioxide sensor module. Based on the data analysis, it can be seen the coverage factor of 1.826 is obtained from Student T with 95% confidence level and the measuring instrument has an expanded uncertainty value Uexp) equal to ± 7,502121 with 95% confidence level so that obtained result of measurement x = (522,3 ± 7,502121)ppm .
