The Design of Domicile Intelligent Alarm System Based on GSM Module Feng Juan(1), Zeng Li-Hua(2) (1. College of Information Science and Technology ; 2.College of Mechanical and Electrical Engineering ,Agricultural University of Hebei ,Baoding, Hebei, 071001) Abstract：A domicile intelligent alarm system based on GSM module was introduced. SCM was a control core of the system；pyroelectric infrared sensor was used for monitoring defense area real-time. When some alarm situation was happened, the system could give an alarm by the way of sound & light & electricity. At the same time, it
would send an alarm message to householder. According to whether the householder was
in the house, the system could switch setting and removing defense by the methods
of encryption and decryption. It proved that the alarm system could meet the needs
of modern domicile anti-theft.
