ARTICLE INFO ABSTRACT Article history: Received 20 November 2013 Received in revised form 24 January 2014 Accepted 29 January 2014 Available online 5 April 2014 Keywords: GSM; AT89C51 microcontroller; PIR; Infrared sensor The improvement of utilization wireless systems in the technology of security and automation such as security house system, wireless communications, productions monitoring process and wireless sensor applications have contributed a large transformation in Global Mobile Communication System (GSM) recently. It is very silent in facilitating and enhancing better performance both in the industry and our daily lives. This paper presents a wireless monitor and control alarm system based on GSM. This system uses microcontroller AT89C51 as the MCU, infrared sensor and a PIR sensor (SN-PIR) to sense the human movement at living room. The operation of proposed system is more efficient and accurate in long distance monitoring by using GSM as a wireless devices from the conventional or alarm system. System design was tested at the room and the data analysis for time response and efficiency of sensor used has being taken. The testing result show that the distances for data sending are more widely and fasting response in any sensor are triggering. © 2014 AENSI Publisher All rights reserved.

Sci., 8(4): 560-566, 2014 INTRODUCTION Global mobile communication system (GSM) has been widely used in telecommunication system. In domestic environment the security house system is used to improve the quality of resident’s life (Sheikh Izzal Azid, 2011). A lot of methods are used in wireless technology in automation house system and it includes the Bluetooth, XBee, Wi-Fi and Global mobile communication system (GSM) application(Y. Tajika 2003, K. Gill 2009, M. H. Jin 2008, L. Ophir 2004, B. Yuksekkaya 2006). The system that used MMS for picture sending for security house system is effective but it could be problems when the 3G, 2G or GPRS for mobile phone not activate and it take a time for picture sending (M.H. Husina 2012, Zhijie Tang 2011). Other than home security system, GSM is also used to turn the street lights. This is based on the use of the RTC to determine the condition of the daylight or night for street lighting (N. Nithyaa 2012). With the implementation a Controlled Integrated Home System by using Global System Mobile (GSM), GSM technology capable solution has proved to be controlled remotely, provide home security and is cost-effective. Thus this paper presents the application of GSM in security house system known as long distance wireless monitoring security house system to overcome the existing application and interfacing in security house system such as wide range and efficient of sensor used. This problem is solved by using the digital IR sensor, PIR sensor, LDR sensor and backup supply in system’s proposed. Other advantage of the system proposed is fasting signal sending by using digital sensor and the correct SMS receive. 2.
