GY-FBG series fiber grating demodulator module can be matched with various fiber grating sensors, through the detection of grating wavelength changes to achieve the purpose of monitoring temperature, strain, pressure and other physical quantities. The wavelength range is from 1525nm to 1565nm, and the wavelength, light intensity and spectral data of the grating to be measured can be reported to the host computer through the serial port RS232.
