Utilization of Galvanic Couples in Wireless Network for Salinity Deposition Sensing

Galvanic couples traditionally used for the evaluation of atmospheric corrosivity are constant monitoring sensors whose output correlates with the deposition of sea salt. This report provides the conversion methodology needed to monitor real-time airborne salinity. The methodology was validated by wireless observations made in two Japanese coastal areas, where a remarkable increase in salt deposition revealed rapid contamination. Additionally, the amount of deposition varied according to distance from the shore. Solar radiation reduced the sensor output and induced a sharp drop in the estimated deposition. These unexpected discrepancies were resolved by considering surface humidity, which was reduced by surface heating.
