With economic and social development and the constant improvement of informatization, people's requirement for life quality has also been improved correspondingly with ever increasing demand for fire protection, burglar alarm and distant power/blackout of household appliances, so various intelligent distant monitoring and alarm systems come into being. This paper introduces the home burglar alarm system based on the GSM message module and elaborates on the entire design scheme of the system's hardware and software, component type, unit circuit design and the entire circuit connection. The infrared induction module and microwave sensor module monitor the invading signals, and when the two modules monitor invading signals at the same time, the system will give an alarm through message to realize the distant alarming function. The test proves that this system is reliable with low cost, so it can be widely applied to modern residence.
