This paper describes the research and development of home intelligent emergency alarm system and its working principle. In the design, STC12C5A60S2 single chip microcomputer is used as the control core of the alarm system, which controls infrared sensor, MQ-2 smoke sensor, SIM900A module, buzzer, LCD1602 display screen and GSM module. The corresponding circuit of each module is designed, and each part of the circuit is integrated to complete the required function.
