Contamination of hazardous chemical gases in the air is an event that needs to be responded to quickly and effectively. This is due to the nature of the gaseous form that spreads in all directions, as well as weather factors such as wind and rainfall that can accelerate the expansion of the contamination area. Therefore, it is necessary to map the chemical gas intensity to determine the condition of the contaminated area. However, the mapping is still being carried out by officers in protective uniforms. This is unethical because it endangers the mapping officer in the long term and is inefficient, due to the nature of the gas which spreads in all directions . Therefore, an UGV (Unmanned Ground Vehicle) device is used to take measurements on the surface, and a UAV (Unmanned Aerial Vehicle) to take measurements at altitude. This UAV and UGV cooperation system brings gas sensors to collect data in contaminated areas. In the design of the sensor system, it is necessary to consider the gas to be measured, the amount of gas to be measured, and the weather conditions in each contaminated area, as well as the air flow due to the vehicle used. In gas testing in contaminated areas, the use of the sensor type can be changed at any time as needed. If there is one type of gas to be measured, it can accommodate many sensors. The room or chamber is needed to place the gas to be measured so that the sensor can perform stable gas measurements. The use of the vehicle will affect the measurement results so that it is necessary to place a good inlet so that the gas to be taken as a measurement sample is far from interference.
