Abstract

With the rapid development of network and information technology and

the improvement of living standards, the current society has made great

progress, and the concept of informatization has become closer to our lives.

With the development of society, family safety has also been paid more

attention. Therefore, everyone will be more concerned about and worry

about the safety of the family. Today there are more and more anti-theft

alarm systems, but now the general security anti-theft system has no function

and cannot automatically alarm. However, this design uses a variety of super

installation and operation are relatively simple.

This system will use 51 single-chip microcomputer as the main control

to make a simulation system of smart home alarm based on GSM short

message module. The starting point is to strengthen the safety of today's

home and make life more comfortable and at ease. When each sensor of this

system detects that it exceeds the value set by the system, it sends an alarm

message to the specified mobile phone number through the GSM SMS

module.
