Abstract: The need for security cannot be overemphasized in today’s modern world, where residential and industrial fire outbreaks, gas leakages, over-current destructions, theft, suffocation from gas accumulations etc. are increasing alarmingly and becomes a major source of threat and environmental hazards. Current security systems in developing countries (if and when available) treat security as only intrusion based, and are of high operational and setup cost and thus the need for a smart and more integrated security system. The GSM based smart security system using Arduino presented employs the Passive Infrared (PIR), MQ2, MQ7 and the DHT 11 sensors in monitoring intrusion, combustible gases, carbon monoxide and temperature threats respectively and also incorporates remote monitoring and control capability. The concept of remote monitoring and control is implemented via the use of SMS and mobile phone calls respectively made possible by utilizing the SIM900 GSM module interface. The two operational modes - internal and external mode reduces the overall operational cost of the system and thus Remote monitoring (SMS), is used only when the owner is actually away, while audio and visual forms of alarms are utilized if he is close by the property. The entire system is controlled by the powerful Arduino Uno. The system resulted in a cost saving, smart, portable and a more efficient way of implementing security alarm systems.
