A polymer optical fiber based on Mach-Zehnder Interferometer (MZI) was proposed and experimentally demostrated for temperature sensor. The MZI comprises two couplers with length of 2 cm and two POF branches with different length which are 5 cm and 3 cm. The jacket of the 5 cm branch was removed to increase the temperature effect on the MZI. Characterization of the sensor was done by putting the sensor in temperature chamber while the two ends of the MZI were connected to light emitting diode (LED) and spectrometer, respectively. The temperature was varied from 40°C to 80°C with an increment of of 5°C. The results showed that the sensitivity is 0.0822 nm/° C with correlation of 97,66%. The MZI sensor has the highest accuracy at temperature of 55°C and the lowest accuracy at temperature of 70°C.
