The technologies ofsecurity are important means to protect the benefit and safety of state and people.Inorder to prevent the events of steal efficiently, we have to own the security system of ourselves. The security mode only by people cant meet our requirement again; the intelligent alarm system depending on new science and technology has been currently developmental trend. The system is a infra-red anti-theft alarm controled by single-chip AT89S52, including infra-red part of the launch, part of the infrared receiver, Pyroelectric infrared sensor,Wireless door magnetic, sensor microcontroller, as well as part of sound and light alarm.The system will alarm when infrared ray has been blocked and the door or window has been opened, through the single-chip microcomputer to control the operation of alarm circuit, and at the same time sound and light alarm, with infrared transceiver test tube, Pyroelectric infrared sensor, Wireless door magnetic sensor. install hidden, can not easily be found; detection signal using pulse signal, energy-saving and anti-jamming. This system can detect a certain person within the scope of the intrusion, security can be applied to determine the scope of the case. Designed using this method of anti-theft alarm and detection in a cost-effectiveness of low-cost best advantages, has broad market prospec
