The present invention relates to a sensor based on an optical fiber bragg grating and an observation system using the same. The present invention is to provide a sensor based on an optical fiber bragg grating, which can observe a weather by using a sensor which does not requires a power supply device, and an observation system using the same. The sensor based on the optical fiber bragg grating includes: an optical fiber having the optical fiber bragg grating; and a magnet unit varying tension of the optical fiber bragg grating. The sensor based on the optical fiber bragg grating senses a change of a wavelength, generated according to the varied tension of the optical fiber bragg grating. |
