Abstract :
Demand for embedded environmental sensors is increasing. One of the key sensor capabilities is the ability to measure salinity. In addition to understanding the environment, a salinity measurement is needed to estimate water density and to convert pressure to estimates of water depth. This outlines a low-cost sensor that combines an H-bridge and digital potentiometer to make an AC resistance measurement suitable for measuring salinity.
