Truck drivers typically work long hours and occasionally in highly polluted settings like mines. Accident prevention at the workplace relies heavily on the health and alertness of the driver. The cabin's air quality can sometimes get worse, which can make drivers tired. A gas detector is a piece of equipment that works as part of a safety system to tell you if there are gases in a certain area. This type of project can communicate with the control system to automatically switch off process and is used to detect gas leaks and other emissions. There are numerous gases that can be harmful to organic life, such as humans or animals, which is why this kind of device is important. Oxygen depletion and combustible, flammable, and toxic gases can be detected with gas detectors. This kind of device is used a lot in industry and can be found monitoring manufacturing processes in places like oil rigs. Gas leak detection is the process of using sensors to find gas leaks that could be dangerous. When a hazardous gas is detected, these sensors typically emit an audible alarm. Early detection of gas leaks, when they occur, is one way to cut losses caused by leaks. One of the many technologies that helps stop gas leaks from harming people even more is the mobile sensor. Another approach to overcoming losses from both material and non-material sources is the creation of mobile sensors. It is anticipated that it will eventually be overcome using a gas sensor MQ-2 as a detector before it has a wider impact. MQ-2 is chosen due to inexpensive and long lifespan. The Arduino IDE is used to implement the C language, which is used to calibrate and configure MQ-2. With a distance of about 0-10 cm between the gas sensor and the point of leakage, it is anticipated that the results will be accurate to 80 percent after the gas sensor has been configured.
