Present invention concerns generally to a sensor or a sensor system for detecting spilling of aqueous liquids, for instance in confined spaces were such is critical such in an airplane. The system of present invention is an early warning system or sentinel for the prevention of corrosion by corrosive liquids. Corrosion caused by corrosive liquids can rapidly change the surface properties of components in engineering structures, and that will finally endanger the functionality of structural parts. However, if monitoring technologies are in place providing continuous information on the presence of corrosive liquids, corrosion treatment and even corrosion prevention can start at a very early stage. Present invention provides such by early detection of corrosive liquids by extended sensors based on the collapse of percolation conductivity (COPC). The term collapse refers to the fact that the transition into the non-conducting state must not necessarily have the properties of a thermodynamically well-defined transition.
