ABSTRACT:
Methods, systems and program products are provided for monitoring an article for fluid exposure. A plurality of liquid sensors is incorporated into an article beneath an outer layer in a furnishing installation. In response to a fluid-detected or no-fluid-detected state, polling the sensors and sometimes other data, a processor component determines fluid exposure, sensor failure and tampering events and stores event data in a memory. Pairs of the sensors are sometimes provided within expected liquid exposure saturation footprint areas. GPS coordinate, weather condition data and structural component positioning data may also be associated with event data.
