Abstract
Gas has become an essential energy in people's lives, Gas leak incident occasionally, gas
leak can make people explode, brought a lot of hidden dangers to personal safety and property
security of people, so to prevent the gas leak detectionthe device has become an urgent need, for
the development of the gas leak alarm detection devices is necessary.
The popularity of computer and microcontroller, and the rapid development of IT, people have
been raised on the family residential environment a higher demand intelligence, information was
introduced to the family, convenient, comfortable and more secure.
The definition of the family of intelligent, in the international community so far there is no
consistent philosophy in the modern urban and rural residential area and the use of
micro-computer, automatic control devices, communication technologies such as the
establishment of a property management center and the security monitoring system, the ultimate
aim is each congratulate get the best solution to meet their requirements. These are sufficient to
show that the security focus. The provisions of the Ministry of Construction, the residential area
should achieve six intelligent, including the implementation of the automated monitoring and
management of security system; burglar alarm system should be infrared or microwave, gas leak
alarms, and other types of alarm devices, based on this paragraph, gas leak detection alarm device
intelligence is imperative.
This system is mainly for conventional gas, liquefied petroleum gas leak detection, alarm. This
system has the following characteristics: with MCU control circuit is simple, cheap, and good
reliability. Enhanced 51 microcontroller, the MQ-2 gas sensors, gas leak emits light and sound
the alarm, this system can be used as a smart home security system!
