基于51单片机的智能家居报警系统

AbstractWith the rapid development of network and information technology andthe improvement of living standards,the current society has made greatprogress,and the concept of informatization has become closer to our lives.With the development of society,family safety has also been paid moreattention.Therefore,everyone will be more concerned about and worryabout the safety of the family.Today there are more and more anti-theftalarm systems,but now the general security anti-theft system has no functionand cannot automatically alarm.However,this design uses a variety of superpowerful detectors to merge with each other to form a cost-effective smarthome alarm system.The model of the detector is:temperature detectorDS18B20,smoke detector MQ-2,infrared human detector HC-SR501.Thissystem is based on the telephone network,using the single-chip language todesign software,using SIM800L module instruction execution speed is faster,the storage space is smaller,the alarm is accurate and reliable,and theinstallation and operation are relatively simple.This system will use 51 single-chip microcomputer as the main controlto make a simulation system of smart home alarm based on GSM shortmessage module.The starting point is to strengthen the safety of today'shome and make life more comfortable and at ease.When each sensor of thissystem detects that it exceeds the value set by the system,it sends an alarm
