It can achieve the goal of real-time monitoring of the home security situation, the monitoring process is very intelligent. At the same time, the GSM module can send alarm information to the house owners remotely. When there is no one in the house, and there are thieves breaking in, the sound and light alarm circuit is going to work, and the buzzer begins to tweet, the LED alarm lights flash meanwhile. According to the main functions of the household burglar alarm system, I come up with the design scheme, and choose the best scheme to design the system. The general design includes two parts: hardware design and software design. The hardware includes seven parts: the MCU minimum system, the GSM text sending module, the heat release human induction module, sound and light alarm module, keys input module, LED indicator module, power module. The MCU is STC89C52, which is produced by Macro Crystal STC Company. The system detects the intrusion signals of thieves by heat release induction module and send the signal to MCU. Then the MCU drives the GSM module to send the alarm information to the house owners. And the LED indicator can show the information on the screen, the buzzer works to response the alarm. The software takes the method of the modular design, the main parts of the software design includes five items: the main subroutine, the interrupt subroutine, the key scanning subroutine, the message sending subroutine, the timi
