The system and techniques disclose herein describe a radio-frequency identification (RFID) capacitance liquid measurement and tag (RCLMT) system for detecting a volume of liquid in a container (liquid level detection), for example an amount of wine inside of a wine bottle. The RCLMT system includes a RFID chip, flexible printed circuit board (PCB), capacitive strips, and adhesive which implements a RFID tag-based sensor that advantageously uses low power and has low cost. Further, a user platform, including the RCLMT system and computer software applications (apps) and a backend system (e.g., cloud service) is described herein. The RCLMT system acts as a passive liquid level detection sensor, which enables the amount of a liquid beverage, such as alcohol, that is inside of a container to be automatically and accurately ascertained.

A method includes sending, by a reader, a radio frequency (RF) signal to a wireless sensor that includes an antenna having a tail section and a head section. The tail section is for placement in an RF limited area for sensing moisture in a first location of a vehicle under test and wherein the head section is for placement in a non-RF limited area. The method further includes receiving, by the reader, an RF response to the RF signal from the wireless sensor. The first RF response includes an indication of adjustment of one or more RF characteristics of the wireless sensor, which corresponds to a variance of the one or more RF characteristics from a desired value, which, in turn, corresponds to a level of moisture at the first location. The method further includes outputting, by the reader, a message regarding the level of moisture at the first location.
