基于单片机的室内安防系统

AbstractAs urbanization speeds up,population density continues to increase,criminals are also more active,and people's demand for family securitycontinues to increase.It has been practical to implement new homesecurity systems through electronic technology,but since similarcomplete systems on the market are either not expensive and cannot beaccepted by the public,or the various functions are not complete enoughand the detection is not accurate enough,so in order to prevent newcriminals and To protect the fire safety of the family,there is an urgentneed for a product that can be recognized by consumers for both familysafety and price,so it is urgent to redesign on the basis of the currentproduct and re-develop a family security system that meets therequirements of the public..This system is based on the 89c51 processor and designed an indoorsecurity system.The system consists of modules such as environmentaldata detection,central processing unit MCU,and SMS notification.It hasthe functions of human body identification alarm,remote notification,smoke alarm and fire extinguishing.Through proteus and WAVEsimulation test and field operation test,it is proved that the system cancomplete the above functions.Key words:Smart home:Remote monitoring:GSM:Shortmessage;MCU;
