Rancang Bangun Sistem Pendeteksi Gas Butana Berbasis Mikrokontroler Arduino Nano Menggunakan PLX DAQ

Abstract

Butane is an organic compound with the formula C4H10 which is an alkane with four carbon atoms. Butane is a gas at room temperature and atmospheric pressure. The term can refer to either of two structural isomers, n-butane or isobutane (also called "methylpropane"), or a mixture of these isomers. But in IUPAC nomenclature, "butane" refers only to the isomer of n-butane (which is the isomer with the unbranched structure). Butane is a highly flammable, colorless, easily liquefied gas that evaporates rapidly at room temperature. The name butane comes from the roots but- (from butyric acid, named after the Greek word for butter) and -ana. In this study the authors used the Arduino microcontroller as the brain of the system and the mq-8 sensor as a means of detecting butane gas levels. The working system of this tool is a system for detecting butane gas. This system serves to see the level of high butane and low butane. The samples measured in this measurement are air concentration, air pollution, CO, and butane. For indication used buzzer and LED. If the butane is low then the LED is ON, if the butane is high then the buzzer is ON, the data will then be connected to the data logger with PLX DAQ which appears on Ms. Excel, then the data will appear on the LCD. And the system re-read data in realtime. From the measurement results, low butane gas is 8% with an air concentration of 5 ppm, while high butane is 17% with an air concentration of 11 ppm and above, the buzzer is an indication of high butane, while the LED is an indication of low butane. It can be concluded that this tool has worked well and can be implemented.
