摘要：

In this paper, a safety of hazardous gas instruments for laboratory experiments was designed using a microcontroller and connected to personal computer to save the data. Here, the carbon monoxide gas (CO) and methane gas (CH4) sensors are applied to the systems to measure the concentration of gases in case of laboratory. Commonly, the gas instruments are used in object tested directly without considering the flow of gases toward the user. Comparing to that system, in order to protect the users' safety from of direct contact with the gases, inlet-outlet pipes and fill-discharge tubes are used in this proposed system. The performance of the proposed system is analysed trough experiments. Some results were presented according to the time of activating inlet to inject the gas. Thus, the effect of changing the gas concentration was analysed.
