近年来，电子技术以及应用需求发展迅速，单片机技术也得到了快速的发展，并且在高集成度，高速度，低功耗以及高性能方面都取得了很大的进步。我们现在完全可以运用单片机、电子温度传感器、热释电传感器、气体传感器等器件构成智能家庭控制系统，使我们的生活更加方便、安全 。

本设计采用一块STC12C5202单片机作为控制核心，将温度传感器获取的温度传输给单片机，通过单片机控制液晶显示屏将当前的温度值显示出，并利用按键设置布防和撤销防盗报警。当设置布防时，热释电传感器将检测入侵者是否闯入。如果闯入室内，热释电传感器将产生信号，无线发送模块将信号发送出去，接收模块接受到告警信号后解码送给单片机进行处理，单片机控制报警灯亮同时蜂鸣器开始报警，从而达到防盗的作用。

     Smart home security alarm system, as a new industry with intelligent household continuously promoted in the market, the smart home market potential is very large, the industry must be a bright future.Therefore, in the domestic many intelligent household production enterprises is to strengthen the recognition of the industry market,Don't strengthens to the enterprise development environment and consumer demand change of deeper research.

     With the development of electronic technology and application requirements, microcontroller technology has been rapid development, and in high integration, high speed, low power consumption and high performance has made great progress.With the development of science and technology, electronic technology has a higher leap, we now can use single chip microcomputer, electronic temperature sensor and pyroelectric sensor, gas sensor components such as intelligent home control system, make our life more convenient and safe.

     This design USES a STC12C5202 single chip microcomputer as control core, transmit to MCU, the temperature of the temperature sensors through the single-chip microcomputer control LCD display the current temperature value shows, and use the Settings protection and alarm.When setting protection, pyroelectric sensors will detect if an intruder broke into.If enter indoor, pyroelectric sensor will produce a signal, wireless transmission module will signal sent out, receive the alarm signal receiving module after decoding to single chip microcomputer for processing, single-chip microcomputer control alarm lights at the same time a buzzer alarm.
