Photonic crystal fiber (PCF) is employed as a refractive index sensor (RIS) for solving a lot of problems in biological, physicochemical, medical, engineering fields and many environmental challenges, where it is using in many industries of food, medicines, chemical materials and diagnoses the materials. The kind of the PCFs was HC-800 with three wavelengths of laser source were used, 638nm, 850nm, and 1550nm that are useful for recording the intended transmitted signal intensity. Therefore, the measured RI was in between the range (1.469-1.455 RIU) at the temperature range (36-70) C for the EBBA and it was (1.621-1.612 RIU) at the temperature range (22-42) C for the MBBA. The results showed that the highest RI sensitivity was 56.815 dBm/RIU for the HC-800 infiltrated with MBBA using the laser of wavelength 850 nm, Also, the highest temperature sensitivity was 0.0281 dBm/C for empty HC-800 using the laser of wavelength 638nm.
