基于STM32的红外报警系统的设计与实现

成都东软学院毕业设计报告AbstractWith the development of society,the progress of the times and the rapid integration ofhigh and new technology,great changes have taken place in people's life.People buy a largenumber of high-tech products.The use of many high-tech products has increasingly becomethe main theme of family life.Therefore,people have higher and higher requirements for thesafety of their environment,especially home safety,We have to keep an eye on uninvitedvisitors.At the same time,infrared technology has become an important part of advancedscience and technology.Because infrared is invisible light,it has good concealment,can beused in day and night,and has strong anti-interference ability.Now many communities havesecurity guards,but there are no such facilities in some rural areas.Therefore,many familieshave installed alarm systems,which effectively protect everyone's property safety.In thisthesis,the design of a monitoring and alarm system using pyroelectric infrared sensor isintroduced.Pyroelectric infrared sensor has the advantages of simple manufacture,low cost,convenient installation,stable anti-theft performance,strong anti-interference ability,highsensitivity,safety and reliability.The anti-theft device is concealed,not easy to be found bythieves,and is convenient for multi-user unified management.This design includes two parts:hardware and software design.The hardware part consists of MCU control module,infraredprobe module,drive execution alarm module,LED control module and so on.The processoradopts single chip microcomputer STM32,and the program is written in C language.Key Words:Pyroelectric infrared sensor,STM32,infrared
