In order to improve the security of home residence, this paper studiesand designs an intelligent home security alarm system, using STC89C51single chip microcomputer as the main controller of the security system,and real-time monitoring by controlling the human pyroelectric infraredsensor and smoke sensor in the case of strangers invading the securityrange and showing signs of fire. Once the abnormal situation is found, theintelligent home security alarm system will start the acousto-optic alarmprompted by the LED lamp and pass through the information processingsystem of the GSM module.
