Photonic Crystal Fiber PCF which is another kind of optical fiber is appeared by Russell. It can beat various obstruction of customary optical fiber, PCFs are uncommon class of optical fiber can be delivered utilizing single material (silica). In this paper LMA-10 PCFS is used, with different lengths as takes after; (2, 2.5, and 3) cm by Fujikura (FSM 60) blend graft machine LMA-10 PCF lengths are joined. The sensor transmission run is checked with laser diode 850 nm sources and OSA as optical range analyzer through sensor fabricating. The experimental result demonstrate that the temperature changing strategy is conversely corresponding with the outside force and the best affectability found for this system is around 0.42 for metal and 0.18 for polymer.
