Intelligent Household Security System Design

Abstract Smart home is a house as a platform, the use of integrated wiring technology, network communication technology, security technology, automatic control technology, audio and video technology to integrate the household life related facilities, schedule to build efficient residential facilities and family affairs management system, improve home security, convenience, comfort, artistry, and realize environmental protection and energy saving living environment.

This design is based on the macro crystalline STC15F2K60S2 microcontroller, external with non-contact IC card module, human body infrared detection module, a smoke sensor module, GPRS wireless data transmission module circuit, mainly realize the fire prevention, anti-theft security function, prevent the harmful gas. The security system by external each sensor module real-time detection, when the detected signal is beyond early warning value, will be treated as early warning signals to single chip microcomputer and single chip microcomputer to appropriate action, such as open a window, buzzer alarm and alarm signals to messages sent to the user's phone.

This simple design lightweight, low cost, reliable detection at the same time, the system power consumption is small, easy to control, has realized the recognition of different alert intelligent security systems.
