该防盗系统使用热释电红外传感器作为人体探测模块，并将防盗系统设计为两个用户可选择的模式：在家模式和离家模式，当处于在家模式时，如果传感器检测到有人进入监控范围，则自动响起门铃提醒用户有访客，就不会发生误把访客当作盗贼的报警事件了；当处于离家模式时，如果传感器检测到有人进入检测范围，则开启声光报警模块进行报警。同时，该系统为密码控制系统，用户通过输入正确密码才可改变模式和解除警报，这也增强了该系统使用的可靠性。(The anti-theft system using pyroelectric infrared sensor as the detection module, and alarm system design for the two user selectable mode: home mode and home mode, when in the home mode, if the sensor detects a person into the monitoring range, will automatically alert the user to a visitor rang the doorbell, will not happen take the visitor as an alarm event of thieves; when in the home mode, if the sensor detects a person into the detection range, open alarm alarm module. At the same time, the system is a password control system that allows users to change their mode and lift their alarms by typing in the correct password, which increases the reliability of the system.)

射频通信lora通信模块相应资料，可以使用1278进行通信无线抄表(Radio frequency communication)

说明：  使用了STM32f103采用采集正弦波 ，使用DMA进行传输，保证数据的实时性(STM32F103 is used to collect sine wave and DMA is used for transmission to ensure real-time data)

si4463长包收发程序，可以完成超过64个字节的收发。(si4463 long packet transceiver procedures can be completed more than 64 bytes transceiver.)

简易秒表，用stc89c52主控制，数码管显示(Simple stopwatch with stc89c52 master control, digital tube display)

基于51单片机，将信息通过无线发射装置发送出去，进行通信(Based on 51 single-chip, the information is sent out via radio transmitting device, communication)

说明：  数码管滚动显示.让数码管在不听的滚动显示(Scrolling LED. So do not listen to the digital control in the rolling display)
