Methods and systems directed to dispensing fluids, such as beverages, using wireless technology are provided. Aspects relate to a beverage dispenser with a dispensing system housing, a valve housing positioned exterior to the dispensing system housing and extending from the dispensing system housing. The valve housing may be configured to dispense a beverage and include self-contained electronics disposed within an interior area of the valve housing. In some embodiments, the beverage dispenser has one or more additional valve housings positioned exterior to the dispensing system housing. The valve housing may be configured to dispense a beverage and include self-contained electronics disposed within an interior area of the valve housing.

An absorbent structure, including a sensor system, can sense and measure the level of wetness contained within the absorbent structure as well as sense and measure environmental conditions. The sensor system may include passive RFID sensors or tags, RFID readers, antenna, a tuning module, a processing module, a memory module and a wireless communication module. The absorbent structure may further include two or more sensors, with a first sensor placed in a first area most likely to first be exposed to liquid and a second sensor spaced apart from the first sensor in an area likely to be exposed to liquid only after the absorbent structure has become more saturated.
