Radio-frequency identification (rfid) capacitance liquid measurement tag system

A method comprising:

• attaching multiple radio-frequency identification (RFID) capacitance liquid measurement and tag systems, wherein each of the multiple RFID capacitance liquid measurement and tag systems to a respective container and generates data associated with detecting a volume of liquid currently held within the respective container;
• transmitting radio waves to the multiple RFID capacitance liquid measurement and tag systems via one or more RFID antennas;
• receiving radio-frequency (RF) signals transmitted from the multiple RFID capacitance liquid measurement and tag systems;
• generating by the multiple RFID capacitance liquid measurement and tag systems via the RF signals;
• communicating the data generated by the multiple RFID capacitance liquid measurement and tag systems via the RF signals;
• reading the data generated by the by the multiple RFID capacitance liquid measurement and tag systems by a RFID reader, using the RF signals received by the one or more RFID antennas;
• wherein each RFID capacitance liquid measurement and tag system comprises affixing capacitive strips to an external surface of a container holding liquid, wherein the capacitive strips are activated as a sensor sensing the volume of the liquid currently held within the respective container;
• coupling a RFID tag to the capacitive strips;
• affixing the RFID tag to the external surface of the respective container;
• and
• transmitting data, by the RFID tag, corresponding to the volume of the liquid sensed by the capacitive strips.

A method, comprising:

• attaching multiple radio-frequency identification (RFID) capacitance liquid measurement and tag systems to a respective container holding liquid, wherein each of the multiple RFID capacitance liquid measurement and tag systems are configured to:
• activate capacitive sensing via radio-frequency (RF) energy to sense a volume of the liquid currently held within the respective container;
• and
• transmit digital data wirelessly via RF signals, wherein the digital data corresponds to the volume of the liquid sensed by the capacitive sensing.
