Abstract
In order to improve the security of home residence, this paper studies and designs an intelligent home security alarm system, using STC89C51 single chip microcomputer as the main controller of the security system, and real-time monitoring by controlling the human pyroelectric infrared sensor and smoke sensor in the case of strangers invading the security range and showing signs of fire. Once the abnormal situation is found, the intelligent home security alarm system will start the acousto-optic alarm prompted by the LED lamp and pass through the information processing system of the GSM module. Send an abnormal text message to the user of the security system at the first time face, and finally realize the purpose of modern intelligent home security alarm.
