An apparatus comprises a sensor having a sensing film and at least two electrodes; and a plurality of electronic components operably associated with the sensor. The sensing film is configured to provide a signal based on humidity immediately prior to contact with liquid water. The electronic components are configured to provide a change in output voltage to trigger an electronic switch that disconnects an electronic device from a power source.
