Abstract
The invention is directed to a water-detection device (100) for detecting a change in an amount of water (W) with respect to a baseline-condition. The water-detection device is configured to compare signal-quality values to baseline-values. The signal-quality values are indicative of a signal-quality metric that is correlated to the amount of water present in a signal-propagation path (S). The baseline-values are indicative of the signal-quality value obtained from the radio-frequency wireless communication signal at the baseline-condition. The water-detection device is configured to provide a water-detected signal (WD) indicative of a possible change of the amount water in the respective signal-propagation path upon determining that respective signal-quality value has been outside a tolerance-range of the baseline-value for a predetermined amount span, without the need of any dedicated water sensor.
