I did the smart home security system from the gas sensors, infrared sensors the body, voice-activated sensors, switches, etc.门磁parts. When there are unusual circumstances, the single-chip microcomputer through sensors placed in each of the first video image acquisition and then to send to the owner, at the same time sounded alarm will sound inside the house. The hardware design is ATmegal6 as the CPU, on the gas alarm system, infrared sensor system the human body,门磁switching systems and voice-activated system to analyze the output state, when any abnormal state of a module, the alarm system through the CPU to the input signal, so as to stimulate alarm sound, and LCD Module which will display the abnormal state. Control system through the operation keys. Through 4 * 4 matrix keyboard to control the whole system running. C programming language on the single-chip, thereby achieving the maximum security, alarm and message transmission function.

I do the intelligence lives at the peaceful against system by the coal gas sensor, the human body infrared sensor, the voice control sensor, parts and so on gate magnetic switch is composed. When has unusual circumstance time, the monolithic opportunity through places carries on the image gathering then transmission in each sensor's visible image for the homeowner, simultaneously in the room will resound the warning sound. This hardware design is takes CPU with ATmegal6, to the coal gas alarm system, the infrared human body induction system, the gate magnetic switch system and the voice control system's output state carries on the analysis, when after any module has the abnormal state, through CPU to alarm system input signal, thus stimulation warning sound, and the liquid crystal will demonstrate that which module has the abnormal state. Through pressed key control system running status. May control the overall system running status through the 4*4 matrix keyboard. C language to monolithic integrated circuit programming, thus has realized the fortification, warning and color letter transmission function.
