Design and fabrication of a labview automated computer-based fire fighting system

Fire detection, control and notification at early stages are of great importance as human life and property is concerned. In this paper we report the design and fabrication of simple, cheap and reliable computer based fire fighting system for use at homes, offices, supermarkets, schools among others. The system comprised of fire detection units made of smoke and temperature sensors, computer display unit, actuators, Bluetooth and GSM networks. Systems functionality was tested by introducing smoke and raising temperature of the surrounding beyond a set threshold levels. With smoke introduced, sensors were activated within 5-10 seconds while with temperature sensors activation took 5-20 seconds. Fire scenes were displayed by the computer 5seconds after detection and respective sprinklers triggered 10seconds later. Bluetooth enabled mobile phone interfaced to the Bluetooth enabled computer via Bluetooth network was able to send a short preset text message to a target remote mobile phone connected to it through GSM network within a period of 60-70 second. With extinction of fire components, respective sprinklers were automatically switched off by the system.
