ABSTRACT

In this thesis was made a household safety control system using a multisensor to detect

the presence of people and the information will be transmitted via wireless to the server. When

the PIR sensor detects a person in front of door, the server will send a notification to the owner

of the house, and if the limit switch indicates the door is opened the server will turn on the alarm

as a warning that there are thieves.

There are two modules that communicate to each other. Module I consist of PIR and

limit switch. Module II is a server of this system that can be taken anywhere.

This sensor system can detect the presence of people from 2 meters in front of the door

or window that has been installed this system. Both modules have a maximum distance to

communicate as far as 91 meters.
