Abstract

Some gases have properties that can be harmful to the human body if inhaled and get
in the human body. The types of gas are LPG, CH 4 , CO and other types of gas. The effects caused
by the gas to humans are shortness of breath, loss of consciousness, and death. In addition, some
gases can cause fires and explosions. Therefore, this research will present the design of a type of
gas detection device based on the MQ-2 gas sensor. The difference between this research and
other research on the design of gas detection is that this research will focus on building a gas
detector that can distinguish several types of gases such as LPG gas, gas arising from pertalite
fuel and alchol. MQ-2 gas sensors are sensitive to these types of gases. The sensor output voltage
in clean air is below 0.2 volts, when there is gas from alcohol which is 0.35-0.69 volts, when there
is gas from pertalite fuel which is 2.7-4.1 volts, whereas when there is LPG gas which is 3-4.4
volts.
