Abstract

Water salinity analysis is critical for water quality monitoring and evaluation in order to guarantee water safety. Unregulated salinity may be harmful to human health, crops, industry, and the ecosystem. The salinity levels in water sources are constantly changing as a result of natural and anthropogenic ecological change. Exceeding specific salt levels might endanger human health, particularly through drinkable water. In this work, we present a simulation of an optofluidic sensor to measure the water’s salinity. We built a design to measure the change in the refractive index in a microfluidic channel based on the dielectric grating. The generated design was modelled to alleviate the manufacturing process of the microfluidic sensor of the saline water. The design was optimized for the range of measurements of the refractive index of saline water by the selection of the material of the sensor.
