In this work, the simultaneous sensing process to detect the salinity and temperature for the given water samples using 1D photonic crystal (PC) periodic structure is numerically investigated. The sensing analytes is considered as defect mode and the whole structure is then tuned to observe the transmittance spectrum over the visible region for the different concentration and temperature of water samples. The observation point is noted as peak wavelength spectral shift over the visible region of band gap spectrum. As a simultaneous sensing process, the salinity concentration is detected for the constant temperature of water samples and salt content of samples kept as constant for detecting the temperature point.
