Sensor for detecting fire-sensing

A fire monitoring system is provided to enable a user to easily prevent fire by applying different colors to normal image data and thermal wavelength image data according to the temperature. A fire preventing system(10) includes a monitoring camera and a fire preventing server, which received thermal images and normal image data from the camera and generates three different alarm sounds according to the temperature. A fire monitoring system(20) includes a panorama camera, a fire monitoring server, a UV(UltraViolet) sensor, and a data collector. The panorama camera photographs an omni-directional color image. Flame and smoke detecting program is loaded in the fire monitoring server. The UV sensor measures the temperature and amount of gas within a region covered by the panorama camera. The data collector receives data from the UV sensor, an IR(InfraRed) sensor, and a gas sensor. A screen output portion(30) includes a digital recorder and a monitor. A self-diagnosing system includes a real time monitoring portion and a central monitoring portion.
