ABSTRACT: This paper presents the design, construction and testing of a world-wide-mobile-call-back burglar alarm system. The principle of operation of this burglar alarm is based on that of a Passive Infrared Sensor as motion detector to sense movement of people, as well as, versatility of an Arduino board and a Global System for Mobile Communications Shield. When the motion of a person is detected by the PIR sensor, the alarm is triggered and a signal is sent to the Arduino board which in turn activates the shield. The shield interfaces with mobile network whose Subscriber Identity Module is used to make call to a pre-programmed mobile line of a property owner. The received call from the particular line thus alert the property owner and/or security personnel of the presence of an intruder on the monitored property
