Abstract
Home Safety has always been one of the objectives pursued. With the advances in technology and sensor technology, people at any time to monitor changes in the environment around them and make up with contingency measures in a timely manner to prevent disasters from happening. For example, in the life of the gas is one of the important energy and cooking or day-to-day use of hot water. However, that neglect could cause carbon monoxide poisoning or gas explosion incident. Therefore, how we can make good use of the gas sensing system to provide real-time early warning sensor for carbon monoxide leakage detection, or too confined caused by the sharp drop in oxygen to give warning predictable and effective to reduce the accident rate that is an important issue. General commercial gas sensor alarm system is employed most of the cable transmission, through the transmission line into the future implementation of data transmission, so in the construction, design and cost-employed on a more convenient and not expensive. In order to improve the shortcomings of this paper the direction of research for the combination of carbon monoxide (CO), carbon dioxide (CO2), methane (CH4) gas combined with high-selectivity multiple-gas sensing module for wireless sensor network system. By composite gas sensors to monitor environmental changes in the gas and with wireless transmission technology, to monitor the information sent to the Center for the Analysis of the data processing, once the monitoring of environmental changes in the concentration of gas will be issued warning message to avoid disaster Took place to achieve real-time monitoring of management
