A simple fiber optic displacement sensor is employed for sensing a purity of honey in distilled water. Concentration of honey is varied from 75% to 100% of honey purity. Prior that, the performances of sensor is first demonstrated by sensing output signal in air. The front slope has a sensitivity of 2.7116 mV/mm while the sensitivity of the back slope is 0.5323 mV/mm. Both of slopes have more than 99% of linearity in range between 0.05 - 0.50 mm and 1.05 - 2.90 mm respectively. By increasing honey concentration, the peak light intensity is linearly increases and gives the measured peak voltage sensitivities about 0.02 mV/%. A real-time measurement, low cost, stability, high sensitivity and simplicity of design promote a well-developed sensor in providing useful parameters in detecting purity of honey.
