BUDGET HOME SECURITY SYSTEM USING GSM AND ARDUINO

Abstract

The need for home security alarm systems nowadays is a serious demand. As the numbers of crimes are increasing every day, a safety measureto help keep safe is required. High end security systems are present in the market but they are not easily accessible. Therefore, a solution is constructing a cost efficient electronic system that has the capability of sensing the motion of the intruders and setting off the alarm. The basic idea behind this project is that all the bodies generate some heat energy in the form of infrared which is invisible to human eyes. But, it can be detected by electronic motion sensor. This paper involves the use of Arduino, motion sensor, buzzer, GSM module and a simple program. The sensor detects any motion in its permissible range and triggers the alarm. It will also send the signal to Arduino which processes the signal and set off the alarm along with detection message will be sent to the owner’s number. With this system, a security alarm can be set up in houses for unwanted intruders.
