A precise GSM and GPS integrated fire alarm system

This paper presents the idea of a fire-alarm system that is based on Global System for Mobile Communication (GSM) and Global Positioning System (GPS). Keeping in view the importance of real-time notifications for safety related issues, we developed a fire-alarm system assisted by GSM and GPS technology. It is challenging to monitor homes at far off places. However, the availability of modern sensors and wireless technology have played an important role to deal with such issues efficiently. Moreover, recent improvements in the field of information technology have provided cost effective and efficient solutions. In this study, a low-cost smart fire alarm system is designed and implemented using Arduino microcontroller that continuously receives temperature and humidity signals form the sensors. In case of any emergency, the owner receives warning messages by GSM with the exact location of incident traced by GPS. To get accurate and improved results, a variable threshold alert algorithm is used for temperature compensation and accuracy.
