A WIRELESS SENSOR NETWORK BASED FIRE PROTECTION SYSTEM WITH SMS ALERTS

Modern buildings are becoming more complex in technical depth and compartmentalization. The average city dweller also has a complex daily living schedule that sometimes span the entire day with rests taken in between. Existing fire detection technologies have not caught up with the reality of today's complex buildings and way of living. This paper proposes a fire detection system that integrates three capabilities, namely, detection, communication and suppression. It was designed with residential buildings in mind but can be adapted for top notch performance in commercial and other kinds of buildings. It seeks to address the salient issue of real time communication in the face of an unpredictable daily routine and first line suppression moves at the onset of a fire outbreak that most advanced fire detection systems in complex buildings of today have failed to address. The proposed system uses a controller, which comprises of a microcontroller and a Global System for Mobile Communication modem to co-ordinate the operation of a network of radio frequency transmission and reception capable smoke detectors, alarms, the main source of power to the building and a water pump (sprinkler system).
