Detection of Gas Leaks Using The MQ 2 Gas Sensor on the Autonomous Mobile Sensor
Gas leaks are one of the big problems in the industrial sector, even starting to spread to other sectors. One of the solutions to reduce losses due to gas leakage is to detect it early when there is a leak. There are already many technologies that help prevent gas leaks harm humans more, one of them is the mobile sensor. The development of mobile sensors is one way to overcome losses both from material and non material. Using a gas sensor of type MQ 2 as a detector, it is expected that later it can be overcome before it has a wider impact. The gas sensor is connected to a mobile sensor and installed in four different directions. MQ 2 was chosen because it has a low price and good durability. Assisted by the SLAM method as navigation and a combination of source seeking and active sensing localization methods as identifiers of leak points, the mobile sensor identifies points of leakage which are on the abnormal boundary. MQ 2 is calibrated and configured using C language, which is implemented through Arduino IDE. After configuring the gas sensor, it is expected that the results of accuracy reach 80% with the distance from the gas sensor to the point of leakage about 0 10 cm.
